For Tim Costello and approved people only
Everyone is pouring billions into reshoring magnet PRODUCTION (MP Materials, Vulcan, USA Rare Earth, Niron), but almost no one is funding the magnetizing, orientation, characterization and design-software EQUIPMENT those plants run on — a layer that is today imported from Japan/China or bought used, and is fragmented across tiny, family-owned, undercapitalized shops. That equipment-and-services layer is unconsolidated, buyable at mid-single-digit EBITDA multiples, and re-rates to 12-20x+ once assembled into a scaled, recurring-revenue platform — the proven buy-and-build arbitrage behind Judges Scientific, Transcat and the Swedish compounders. Tim Costello — who ran Global Operations at Applied Materials (the literal namesake), launched GM's EV1, is Shingo Hall of Fame on lean, and already built-and-exited a roll-up of a fragmented family-owned industry (BHI → Zonda → CoStar, $800M) — is the operator a founder sells to and a PE partner backs, with Polymagnet's programmable-magnet IP as the crown jewel that cuts rare-earth intensity and de-commoditizes the whole platform.
The thesis
THE WHITE SPACE (externally validated). US magnet-production reshoring is now a multi-billion-dollar, federally-backed build-out — MP Materials (Pentagon its largest shareholder, $400M preferred + $150M loan + 10-yr NdPr price floor; Apple $500M supply deal), Vulcan Elements (>$1B Nov 2025 incl. a reported ~$620M DoW loan + CHIPS + Commerce equity), USA Rare Earth (Stillwater OK sintered-NdFeB line), and Niron (rare-earth-free). But the magnetizing / orientation / characterization / QC / design-software EQUIPMENT those plants depend on is imported (Japan's ULVAC is re-shoring its OWN furnace production; USA Rare Earth bootstrapped on USED NdFeB equipment) and takes years to assemble (Adamas Intelligence). No US/Western-owned, consolidated equipment-and-service platform exists. That is the picks-and-shovels gap Tim's roll-up fills — reported fact, not assertion.
THE INDUSTRY IS GENUINELY FRAGMENTED. The MMM 2026 exhibit floor is a live roster of the thesis: of ~13 exhibitors, roughly 9 are tiny family- or founder-owned equipment/instrument shops — Hirst (UK, ~60 yrs, private), GMW (CA, employee-owned, ~20 staff), Group3/G3 (NZ, owner-operated, ~7 staff), Hinds (OR, Hinds family since 1971), NanoMagnetics (founder Prof. Oral). Tim's own slide-7 targets (Oersted, 360 Magnetics, Magnetic Instrumentation, Bunting; Hirst, Eckel, MAGSYS) map onto real, small, independent firms. The pure pulse-magnetizer market is only a few hundred $M — so the roll-up case rests on margin, recurring service/calibration/consumables and strategic position, NOT raw TAM.
THE ECONOMIC ENGINE — multiple arbitrage plus a recurring-revenue re-rate. Small, family-owned instrument/equipment businesses transact at roughly 4-7x EBITDA (Judges Scientific pays ~5x EBIT; LMM midpoint ~5.5x), while a scaled, diversified instrument platform is valued at ~12-20x+ (Judges ~11.6x EV/EBITDA, Transcat ~18.9x, Veralto ~16.9x, Spectris taken private by KKR at 19.5x EBITDA). A Bain-referenced finding holds that reducing the average entry multiple contributes ~8 percentage points/yr of equity-value CAGR — i.e. the arbitrage, not operational magic, is the dominant return driver. The second lever is converting a hardware cost-of-goods business into software + ISO-17025 calibration + data/traceability + design-IP royalties; across 400+ deals, hardware traded ~1.4x revenue vs software ~3.0x. Treat all multiples as a diligence FRAMEWORK to re-source (PitchBook/CapIQ), never as committed numbers.
WHY NOW IS ACUTE. China controls ~70% of rare-earth mining, ~90% of processing and ~93% of magnet manufacturing (CSIS) and in 2025 weaponized it: April 2025 controls on 7 medium/heavy REEs, an October 2025 expansion reaching foreign-made magnets with >=0.1% Chinese-origin REE AND magnet-making technology/equipment, and from Dec 1 2025 denial of licenses to foreign military-affiliated buyers. EO 14241, DPA Title III, the EU Critical Raw Materials Act (10/40/25/65 benchmarks) and a live US Section 232 probe on permanent magnets all push subsidized Western magnet + equipment capacity. A Western-owned magnetizing + QC capability reads as a national-security asset — which supports premium multiples and government/PE co-investment.
CONSOLIDATION HAS ALREADY STARTED — the window is closing. PE is already running this exact play one adjacency over: Arcline's DwyerOmega precision-measurement platform (Dwyer 2021 + Omega carved from Spectris 2022 + a string of bolt-ons) pulled magnetics IN via Lake Shore Cryotronics (family-owned since 1968, acquired June 2026). Carlson Private Capital bought Quantum Design (Oct 2024), which then took Oxford Instruments' NanoScience unit for GBP60M. KLA holds MicroSense + Capres (2019). The measurement side is being professionalized by sponsors NOW — but no one owns the magnetizing + design-software + domestic-service core. Correct the record: DwyerOmega's owner is Arcline (PE, >$30B AUM), NOT Novanta.
WHY TIM, NOT A FINANCIAL SPONSOR. Family founders in this segment sell to a steward/operator who understands the technology and keeps the business alive — Tim's exact profile (Applied Materials Global Ops; GM EV1; Shingo Hall of Fame lean; BHI 1,300-builder roll-up exited through Zonda to CoStar at $800M — the exit chain is independently verified; the AMAT/GM/Shingo bio is self-reported on the deck and should be backed with a press/LinkedIn citation before external use). The value creation here is operational (build US service/calibration, centralize engineering, bolt on software), which is Tim's toolkit — and Polymagnet's programmable-magnet IP cuts rare-earth intensity, selling the exact China-exposure reduction every reshoring customer is buying.
STRATEGY: build a US nucleus first. Fix the deck's own 'weak US support' gap with a domestic magnetizing cluster — Oersted (OR), Magnetic Instrumentation (IN), 360 Magnetics + QT (CA), GMW (CA), Group3's new Cerritos arm — assembled without crossing borders, then extend into EU magnetizing (MAGSYS, Hirst) and the global measurement standard-bearers (Group3, GMW) for metrology credibility. Hold Judges-style entry discipline (hard 4-7x cap, ROTIC/IRR hurdle >15%): Judges' own post-mortems show IRRs collapse above ~7x EBIT without organic growth, and sellers raise prices once a roll-up is known. The first diligence workstream is the quantified value-creation bridge the roll-up deck itself admits is missing (entry multiples, target EBITDA, synergy stack, exit multiple).
The tailwind
Why the magnetics-equipment layer is strategically scarce right now.
China's near-monopoly is the structural scarcity driver — and it is being weaponized, which makes a Western-owned magnetizing + QC capability effectively a national-security asset (supports premium multiples and government/PE co-investment).
2025 export controls reached not just rare-earth magnets but magnet-making TECHNOLOGY and equipment, and (from Dec 1 2025) deny licenses to foreign military-affiliated buyers — directly raising the value of Western-owned equipment capability. (Expiry timeline unsettled: Nov 10 2026 vs a reported Jan 10 2027 extension — unconfirmed in official notices; cite MOFCOM directly.)
Unprecedented government + strategic capital is behind Western magnet PRODUCTION — the customer base for a magnetizing/calibration platform. (Exact figures vary by source; verify vs SEC filings.)
The US 'magnet gap' is the near-term account list: ~48,000 MT consumed vs ~300 MT domestic output (directional, trade-press), pulling >38,000 MT/yr of announced US NdFeB capacity on-line — every new plant needs magnetizing + ISO-17025 calibration/measurement gear.
The equipment layer is the overlooked, un-funded bottleneck — reshorers depend on Japanese/Chinese equipment makers or used gear, and standing up capacity 'requires years.' This is the white space, now third-party-validated.
Policy pull on two continents is locked in: EO 14241 + DPA Title III (US), the EU Critical Raw Materials Act (10% extraction / 40% processing / 25% recycling / max 65% single-country by 2030, rare earths named strategic), and a live US Section 232 probe covering permanent magnets (outcome not yet public).
Market sizing (cite as RANGES — vary ~2x by scope): permanent-magnet materials ~$28-55B in 2026 (~6-8% CAGR, NdFeB ~64% share); magnetic test & measurement ~$3-4B in 2025 to ~$6-8B by 2032-34; pure magnetizing equipment only ~$0.37-0.41B (so sell on margin/services/strategic position, not raw TAM).
The playbook
The comps a PE partner already believes in. Tim's thesis is this playbook, aimed at magnetics.
THE LESSON IN ONE LINE: The discipline is the whole business — the multiple you pay is the moat, and the one deal that breaks the rule can undo a decade of compounding. Five transferable takeaways for a magnetics-equipment roll-up: 1) PRICE DISCIPLINE IS NON-NEGOTIABLE, AND IT IS THE STRATEGY. Judges' edge was never clever operating magic — it was buying niche #1/#2 manufacturers at 3-6x EBIT and refusing to go higher. The spread between a low private entry multiple and the higher multiple the platform earns is the compounding engine. For fragmented magnetics-equipment firms (Halbach-array makers, magnetizers/fixturing, measurement/metrology, custom assemblies), set a hard multiple cap up front and publish it to your PE partners. 2) THE CAUTIONARY TALE IS REAL AND RECENT. The one time Judges broke its own ~6x cap — Geotek, ~£80m at ~7x in 2022, its "transformational" deal — group after-tax ROTIC collapsed 17%->9%, the stock fell ~two-thirds from its 2024 peak, and analysts re-rated it "a less capable acquirer." Tim's takeaway: one oversized, over-multiple, cycle-peak acquisition can erase years of disciplined gains. Be willing to WALK from the marquee deal. 3) DECENTRALIZE — BUY IT, DON'T BLEND IT. Keep founders, brands, engineering teams and customer relationships intact; impose only financial control (cash, capital allocation, debt paydown) from a deliberately tiny centre (~£4m/yr at a ~£145m-revenue group). Magnetics firms are deep-domain, relationship-driven engineering shops — integration destroys exactly what you paid for. This also makes the platform a friendly home for retiring founders, which wins proprietary (non-auctioned) deals. 4) STRUCTURE PRICE RISK OUT WITH EARN-OUTS AND DEBT ~50/50. Pay vendors for profit actually delivered, fund ~half with cheap debt sized to the target's own cash flow, recycle free cash into the next deal. Avoid paying full freight for peak-cycle earnings — critical because scientific/industrial capex (and magnetics demand tied to EV, motors, medical, defense R&D) is lumpy and cyclical. 5) GO SLOW AND DIVERSIFY THE NICHES. ~1 deal/year, small tickets, many independent niches. Judges' recent pain was partly customer/contract concentration (lumpy "coring expedition" revenue). A magnetics roll-up should spread across sub-niches and end-markets so no single cyclical customer or contract swings the group. NET: Pitch the PE room on the multiple-arbitrage + autonomy flywheel Judges proved over ~20 years and ~86x — but lead with the discipline guardrails, because Judges itself just demonstrated, in public and in the share price, what happens when you relax them.

The companies that earn premium multiples (and attract KKR-type capital) do NOT win on vision — they win on a repeatable, teachable OPERATING SYSTEM applied to every acquisition. Before the roll-up story sells to PE, build and name your "Magnetics Business System": the specific playbook (sourcing, lean, pricing, cross-sell, new-product cadence) you drop onto each acquired magnet/equipment shop to lift its margin the way DBS lifted Danaher +600bps. The system is what de-risks the thesis for a sponsor. Second: magnetics EQUIPMENT alone is project/capital-heavy and will earn a low, cyclical multiple. The compounders escaped that by deliberately engineering a recurring, high-margin layer — Roper (76% software), Danaher (consumables). Polymagnet's programmable-magnet IP is your software-equivalent, high-margin, royalty/licensing asset; pair it with service, calibration, measurement, and consumable/material streams so the platform is re-rated as "instrumentation + recurring IP," not "equipment." That mix shift is the difference between an 8x business and a 20x one. Third: your setup is exactly what this capital prizes. AMETEK buys "leading positions in niche markets"; Halma buys "global market niches." Fragmented magnetics, full of niche leaders, IS the ideal substrate — frame the thesis in their language. And the exit evidence is live and specific: KKR just paid ~£4.7bn for Spectris in a contested 2025 auction against Advent. Private capital is actively competing for precision-instrumentation platforms right now — that is your comp and your exit-multiple proof point for the war-room. Fourth, the checklist to walk into PE conversations with: (1) the named operating system, documented; (2) a deep proprietary bolt-on pipeline at single-digit-to-low-teens multiples (show the names, not a TAM slide); (3) a recurring-revenue / IP-royalty layer with pricing power; (4) organic growth, not just acquired — the market pays a premium for the organic half (Roper's 6% organic inside 14% total); (5) niche leadership + clean financials + an integration bench. Lead with the system and the pipeline. The "Applied Materials of Magnetics" line lands only when it sits on top of those five proofs. CAVEAT to keep the war-room honest: every company figure above is sourced to filings/IR/press; the EV/EBITDA multiple RANGES are illustrative estimates, not live quotes (web-search budget was exhausted this session) — label them as such and refresh with current data before any number goes in front of a sponsor.
SOURCED (primary filings / company IR / cited press): - Danaher FY2024: sales $23,875M (flat vs $23,890M FY23); gross margin 55.7%→59.5% (2019→2024); adjusted operating margin 22.3%→28.6%, i.e. +600bps+; Abcam acquired Dec 2023 for ~$5.7B; Masimo agreed at $180/share (announced, into Diagnostics segment).

[halma.com/investors] - Spectris: KKR won a 2025 auction over Advent; KKR offer valued Spectris at ~£4.7bn incl. debt (~$6.46bn) vs Advent's earlier ~£3.73bn; precision-instrumentation maker, founded 1915, ~7,600 employees; UK court approved 2 Dec 2025. [en.wikipedia.org/wiki/Spectris + cited press] ILLUSTRATIVE / ESTIMATE (NOT sourced live — label as such to Tim; multiples move daily and I could not pull current quotes this session): public instrument-compounders have historically traded in roughly the ~18–25x EV/EBITDA / high-20s–30x P/E range, while the niche bolt-ons they buy typically transact at ~8–14x EBITDA. The gap between those two ranges is the "multiple arbitrage." The Spectris £4.7bn take-private is a hard, sourced data point on what a scaled precision-instrumentation platform fetches; the exact implied EV/EBITDA is an estimate pending Spectris's last reported EBITDA. Treat all multiple ranges as directional, not quotes.
The prize isn't magnetics innovation — it's the multiple. Magnetics equipment is structurally the same as the scientific-instrument and T&M niches Judges, Halma, AMETEK and Danaher have already consolidated: hundreds of sub-scale, founder-owned, high-gross-margin, IP-rich B2B makers with no natural exit. Value is created by (1) buying them at mid-single-digit EBIT/EBITDA multiples with disciplined, decentralized M&A, (2) assembling them into one branded, diversified platform that institutions and PE value at 20x+ EBITDA, and (3) letting re-rating + modest leverage + organic growth compound. That is a ~5x-in / 20x+-out spread, and it is a de-risked playbook — not a theory — because four separate companies have run it to scale in adjacent instrument verticals, and KKR just paid £4.7bn to take one (Spectris) private. The discipline that makes it work, and the exact lines to carry into a PE conversation: never overpay at entry (cap ~7x EBIT — the deal engine dies if you chase); keep leverage at or below ~3x the target's EBITDA; keep acquired founders' teams running their own businesses; buy roughly one good company a year, not one bad empire; and position Correlated Magnetics / Polymagnet as the branded technology anchor the platform compounds around. The pitch to a sponsor: a proven consolidation model applied to a vertical (magnetics) that nobody has rolled up yet — all of the arbitrage, none of the "will the playbook work" risk. One caveat to state plainly to Tim and to PE: the cleanest entry-multiple evidence (4-6x EBIT) comes from investor analyses of Judges rather than audited disclosure, and the public comps are an aggregator's figures — anchor the model on Judges' audited annual report and on a banker's fairness-opinion comp set before any number goes into an LOI or IC memo.
ENTRY (small private niche instrument/T&M maker) — what consolidators actually pay: - Judges Scientific paid multiples: average ~4-6x EBIT; full range 3x (financial-crisis low) to ~7x (Geotek, 2022, its largest at £80m); ~7x is the stated ceiling. [per three independent investor write-ups — ltir.substack, compoundandfire.substack, riccardosorelli.substack — mutually consistent; secondary, confirm vs. Judges' annual report] - Typical Judges deal size ~£6-12m. [riccardosorelli] - Leverage at entry: up to ~3x target EBITDA; balance in cash + earn-out. [all three] - Derived entry EV/revenue: first deal FTT (2005) had £3m sales / £0.75m EBIT, bought at 5x EBIT = ~£3.75m → ~1.25x revenue.

THE LESSON (specific, for the war room): 1. The thesis is validated — but the crown jewel is already taken. "The Applied Materials of Magnetics" is a real, precedented play (KLA, Nova, AMETEK, Halma, Judges all prove instrument roll-ups compound). BUT the obvious pure-play anchor, Lake Shore Cryotronics, is already inside Arcline's DwyerOmega. So Tim is not first to the best measurement asset. Two consequences: (a) move on the remaining fragmented independents before Arcline/AMETEK/KLA sweep them, and (b) don't position as a Lake Shore competitor you must out-buy — position as the consolidator of everything Lake Shore's owner ISN'T prioritizing (magnetizers, field generation, Helmholtz/coils, materials, test systems, calibration/service), i.e., own the full magnetics STACK, not just metrology. 2. Know which rival you're facing on each target, because it changes the price. On semiconductor/magnetic-recording-metrology targets you'll lose to KLA/Nova/AMETEK (they pay revenue-synergy prices). On broad niche-instrument targets you compete with Halma/Judges/AMETEK on discipline. On platform-scale deals you face Arcline and KKR/Spectris money. Tim's edge cannot be price — it has to be operator credibility (CMR/Polymagnet domain depth), speed, and being the trusted "good home" for a retiring founder. That's the same edge Halma and Judges actually win on. 3. Multiple arbitrage is the whole game, and so is discipline. The return comes from buying sub-scale founder businesses at mid-single-digit EBITDA and re-rating them inside a platform worth mid-teens+. But Judges Scientific's market cap fell ~41% — proof that roll-ups de-rate hard when they overpay or growth stalls. The binding constraint is entry multiple discipline, not deal volume. Underwrite every bolt-on to stand alone. 4. MMM 2026 Honolulu this week is the pipeline, not just a booth. The exhibitor floor is literally the fragmented target universe — sensor, gaussmeter, magnetizer, Helmholtz, materials, and test-system makers, many founder-owned and near succession. Use the show to build the target map (founders, ages, succession risk, rough size) and to pre-position Polymagnet/CMR as the friendly consolidator, so PE conversations have a named, sequenced pipeline rather than a thesis. Spectris→KKR (Dec 2025) and the Advent/KKR bidding war show PE appetite for instrument platforms is hot right now — the window to raise and anchor is open.

HALMA — HLMA (stockanalysis.com/quote/lon/HLMA/; en.wikipedia.org/wiki/Halma_plc): FY2026 revenue £2.58B (+14.87%), earnings £372.3M; market cap £13.02B (Oct 30, 2026); ~9,000 employees; founded 1894; three segments (Safety / Environmental & Analysis / Healthcare), ~34+ named subsidiaries. JUDGES SCIENTIFIC — JDG (stockanalysis.com/quote/lon/JDG/): FY2025 revenue £145.8M (+9.13%); earnings £5.5M (down ~47%); market cap ~£226M (DOWN ~41.5% — notable de-rating). Two segments (Materials Sciences + Vacuum); founded 2002; 791 employees. AIM: JDG. (Its famed low-multiple buy-and-build discipline is widely reported but a specific target EV/EBIT multiple was NOT confirmable in-session — judges.uk currently redirects to an unrelated site.) METHOD NOTE: WebSearch budget for the session was exhausted before this task ran; all figures above come from direct WebFetch of the cited pages (Wikipedia, company sites, stockanalysis.com) and two live domain-redirect confirmations. Treat every item marked "NOT confirmed in-session" as needing a second source before it goes in front of a PE counterparty.
The single closest proven analog and the entry-discipline anchor: a listed buy-and-build of niche scientific-instrument makers. Copy its template line-for-line — hard 3-7x EBIT entry cap, ~50% debt per deal, leverage capped ~3x EBITDA, cash swept to repay acquisition debt then re-levered, decentralized hold-forever, asset-light. Its own post-mortems show IRRs collapse above ~7x EBIT without organic growth — so entry discipline IS the credibility test.
~25 niche instrument businesses acquired since 2005 at an average ~5x EBIT (range 3-7x; In Practise pegs ~6x avg vs Halma ~7.5x). 19-yr revenue CAGR ~19%, EBIT CAGR ~23%; ROTIC averaged ~16% since 2007. Trades ~11.6x EV/EBITDA. CAUTION: cyclical — H1-2026 profit fell 66% and ROTIC dipped below 10% in a soft patch.
The best 'what a scaled platform is worth' anchor — a diversified, recurring-revenue instrument group attracts both PE and strategics at a large premium, and a bidding war (Advent vs KKR) proves the demand.
KKR's July 2025 recommended cash offer of GBP40.00/share (~GBP4.1bn equity, ~GBP4.7-4.8bn EV) = 19.5x FY2024 Adjusted EBITDA / 23.0x Adjusted EBIT. Final recommended price rose to ~GBP41.75/share (no published EV/EBITDA for the final price). For contrast, listed peers Oxford Instruments ~10x, Renishaw ~13x.
The cleanest fragmented-market roll-up POSITIONING comp — 'acquirer of choice in a fragmented market' of tiny calibration/instrument-service firms, winning on fast repeatable integration. Almost exactly Tim's structural picture, with the added lever of centralized US sales/service.
Targets mostly $0.5M-$10M revenue; ~$1.4bn addressable, highly fragmented calibration market with a long tail of $0.5M-$5M providers. Re-rated to ~2.8x revenue / ~18.9x EV/EBITDA.
THE live proof the thesis is real AND already being executed in magnetics — and the competitive clock. A PE platform (Arcline, >$30B AUM) rolling up precision measurement pulled a family-owned (Swartz family since 1968) magnetics/cryogenic-measurement maker IN. Template: operator-led platform + PE capital + bolt-ons. CORRECT THE RECORD: owner is Arcline, NOT Novanta.
Acquired June 10 2026; terms undisclosed (Houlihan Lokey advised). DwyerOmega bolt-ons include Dwyer (2021), Omega (carved from Spectris 2022 at ~$525M), Process Sensing Technologies, Burns Engineering (Jan 2026), SOR Controls Group, Lake Shore (June 2026).
A SECOND PE-backed consolidator already buying in cryogenic/magnetics measurement, now running its own bolt-on strategy — reinforcing that the attractive measurement assets have competing buyers and a closing window. Also a usable valuation anchor for thin-margin magnetics hardware.
QD acquired Oct 11 2024 (Houlihan Lokey advised; Yukon Partners junior capital). QD then agreed to buy Oxford Instruments' NanoScience unit for GBP60M (~1.0x revenue on ~GBP59M sales / ~GBP1M adj. operating profit) — frame Polymagnet's software/IP/recurring layer as what lifts a platform above a ~1x-revenue hardware multiple.
The hardest evidence the buy-low/trade-high spread PERSISTS across decades and is the dominant return driver — back it with the Bain-referenced finding that entry-multiple reduction is worth ~8%/yr of equity CAGR.
Lifco has acquired at ~7.5x EV/EBITA on average while the group trades >20x EV/EBITA; Addtech's older deals ~5x EV/EBIT, now ~7x, while valued up toward ~30x EV/EBIT. (Substack/advisory-sourced — re-check vs primary reports before quoting as hard fact.)
The 'operating system' narrative PE expects, and the credible basis for 'the Applied Materials of Magnetics': buy niche #1s, improve them with a repeatable system (DBS/kaizen), sweep cash, buy again, periodically spin out. AMETEK/KLA are also plausible eventual strategic exit buyers for a built-up platform.
Roper targets mid-teens cash-flow compounding (doubling ~every 5 yrs). AMETEK: acquisitions ~73% of $8.6bn deployed since 2010; deal-level entry multiples not disclosed. Halma: ~7.5x EBIT bolt-ons, run at ~1x net-debt/EBITDA, ~GBP515m across 6 deals in 2026.
The multiple math above is an illustrative framework drawn from public comps, not a forecast. Real numbers come from the deal model.

This week
Concrete moves on the floor in Honolulu that advance the roll-up — partner and customer framing, never "I want to buy you."
Outreach
Ready to adapt. Warm, operator-to-operator, no deck attached.
Jim — we're your next-door neighbor at Booth 11. We write multipole patterns into magnets with capacitor-discharge pulses, and you've built pulse magnetisers and pulsed-field magnetometry for decades. I'm genuinely curious: could a PFM08 tell us anything useful about a magnet carrying a few hundred maxels? Happy to do a demo swap — I'll show you PolyDesk at 11 if you'll walk me through the PFM at 12. And I'll be at your GR-05 FORC poster Friday.
Quick question from someone who makes an unusual magnet: how would you check a programmed / multipole magnet, part by part, at line speed? And two follow-ups — who runs your North American sales and service today, and do you co-develop or OEM? (Priority order: Spin Sensing Factory first — their CE-04 paper reads a magnetization pattern back with TMR + deep learning, the most complementary work on the floor.)
Robert — fellow magnet people. You've built a real global platform through Master Magnets and Magnet Applications; we've built programmable-magnet IP and a design-software stack. Worth comparing notes on where the industry is heading and whether there's a way our capabilities complement yours. (Internal note: Bunting is itself a serial acquirer post the June 2025 ownership transition — treat as a partner/merger-of-equals conversation, price accordingly, never a soft target.)
We design multipole magnet patterns and are building out US magnetizing, characterization and ISO-17025 calibration capability. Your magnetizers / fluxmeters / accredited lab are exactly the kind of capability our customers need domestically. Could we find 20 minutes to talk about co-development or supply — and, where it fits, a deeper partnership? (Internal: Magnetic Instrumentation = clean, professionally managed, accredited lab — lead here. Oersted = verify Oregon SOS status FIRST, site is dead, possible cheap asset pickup. QT/Quadrant founder Ron Zichterman, ~30 yrs = succession lever.)
Dr. El-Ghazaly — your work on reconfigurable magnetics and micron-scale Halbach patterns is the closest thing at MMM to what we do with programmed maxels. How do you pattern and measure a Halbach field at that scale? Would love 10 minutes and to show you our approach at Booth 11. (Also: Gachon's Won-Ho/Kyu-Seob Kim — the only post-assembly-magnetization/yoke-design group here; and Ames/CMI's Ikenna Nlebedim — the DOE rare-earth-reduction hub, directly on our material-reduction thesis.)
The thesis in one line: $2B+ is funding US magnet PRODUCTION, but the magnetizing/orientation/characterization/software EQUIPMENT those plants run on is imported or bought used, fragmented across tiny family-owned shops, and buyable at ~4-7x EBITDA — re-rating to 12-20x+ as a scaled, recurring-revenue platform (Judges, Transcat, Spectris, the Swedish compounders). PE is already running this one adjacency over (Arcline/DwyerOmega just pulled magnetics in via Lake Shore; Carlson owns Quantum Design) — but no one owns the magnetizing + design-software + US-service core. An operator who ran Applied Materials' global ops and already exited a fragmented-industry roll-up, with differentiated programmable-magnet IP that cuts rare-earth intensity, is the one to assemble it. First workstream is the quantified value-creation bridge; all multiples here are an illustrative framework to re-source in diligence.

Adds a best-in-class DIGITAL MAGNET-METROLOGY / QC leg to an "Applied Materials of Magnetics" equipment platform. Highly complementary to Polymagnet / Correlated Magnetics Research with essentially no product overlap: Polymagnet programs and magnetizes (multipole / correlated magnets), Eckel measures and certifies — the natural "you magnetize it, you must measure it" line pairing. Strategic prize: Eckel's Robograph is the de-facto GLOBAL STANDARD instrument for the Bosch permanent-magnet QC spec (3 139 918 950), run both inside Bosch and across its supplier base worldwide. Its customer/reference list reads like an industry channel map: Bosch (multiple global sites), VW, Valeo, Brose, Nidec, Dunkermotoren, Bender; plus magnet makers Hitachi Metals (US+JP), TDK (CN+US), DMEGC, Ugimag (FR/BR/KR/MX/CN), TRIDELTA, SINOMAG, Hunan Aerospace Magnet, JPMF, KAMCO, Ssangyong Materials, Pacific Metals, POSCO/RIST. Brings (1) a standards-defining metrology product, (2) genuine digital-DSP IP that leapfrogs incumbents' analog integrators (Magnet-Physik, Brockhaus), and (3) deep sticky OEM + magnet-maker relationships, with 10-year service guarantees = recurring aftermarket. Main caveat is scale/key-man concentration, not strategic fit.
"Werner — I'm Tim Costello from Polymagnet in the US; we program and magnetize multipole magnets. I just spent a week at the MMM conference and it struck me again that your Robograph is the instrument the whole industry quietly trusts to decide whether a magnet is actually good — you turned the Bosch flux spec into everyone's standard. I'd genuinely just like to meet the two engineers behind it and compare notes on where magnet measurement goes next. No agenda beyond that."
Dear Mr. Eckel, I've just come back from the MMM magnetics conference in Honolulu, and once again every serious conversation about magnet quality came back to the same thing — can you actually measure it — and your name was behind the answer. For more than thirty years you and Martin have done that better than anyone: the Robograph is the quiet standard that Bosch and half the magnet makers I met this week run their quality on, and the digital work under the hood is years ahead of the old analog boxes. I run Polymagnet (Correlated Magnetics Research) in the United States — we program and magnetize correlated magnets — and I've been trying to bring the best magnetics-equipment people together rather than watch this field stay as fragmented as it is. I'm not writing to pitch you anything; I'd simply like to meet the people behind the instrument and hear how you see the next ten years of magnet measurement. If you're open to it, I'd happily come to Grenzheim, or we could start with a call at whatever time of day suits you best.
Strong COMPLEMENT, minimal overlap with Polymagnet/Correlated Magnetics. CMR/Polymagnet makes programmable patterned permanent magnets (maxels); GMW brings the surrounding equipment layer a magnetics platform needs: (1) magnetic test & measurement + field-mapping instrumentation — the exact tooling used to characterize programmable magnets, an obvious internal + cross-sell synergy; (2) a NIST-traceable / ISO-17025 calibration lab (rare, sticky, recurring-revenue infrastructure); (3) 40+ years of trusted channel + applications engineering into accelerators, MRI, EV/power electronics, spintronics and materials-research labs — instant distribution reach for the platform's other product lines; (4) its own electromagnet & magnet-systems engineering. For an "Applied Materials of Magnetics" roll-up, GMW is a cornerstone "measurement + channel + calibration" node rather than another magnet maker — it makes the platform's other acquisitions sellable and serviceable. Light overlap only in permanent-magnet supply.
(At Booth 2, to Brian Richter.) "Brian — Tim Costello, Correlated Magnetics, the Polymagnet shop. I had to come find you: GMW is the name that keeps coming up when I talk to accelerator and MRI people about who actually understands magnetic measurement end-to-end. I'm spending real time trying to knit this fragmented industry together so the independents can set the standard instead of fighting over scraps — not pitching anything, genuinely just want to compare notes on where magnetics is heading. Can I buy you and Tom a coffee while we're both stuck in Honolulu?"
Brian — great to finally meet you and Tom at Booth 2; the field-mapping walkthrough was the most useful 20 minutes I had all week. I run Correlated Magnetics Research — the Polymagnet folks — and over the last couple of years I've been quietly building what I think of as the "Applied Materials of magnetics": bringing the best independent magnetics shops under one roof so we stop competing on scraps and start setting the standard together. GMW is exactly the kind of company I keep circling back to — four decades of trust in accelerators, MRI and power electronics, a real applications bench, and a calibration lab nobody else can match. I'm not asking for anything today; I'd just like to keep the conversation going and understand what the next chapter looks like for you and the team, whether that's partnership, co-selling, or something bigger down the road. Could I grab 30 minutes by phone in the next couple of weeks? And either way — our Polymagnet side would love to get our programmable magnets onto your mappers.
Near-ideal bolt-on for a magnetics-equipment roll-up ("Applied Materials of Magnetics"). Hirst supplies exactly the capital equipment and metrology that surround magnet production: industrial magnetisers/demagnetisers, pulsed-field magnetometers (the gold standard for characterising high-coercivity rare-earth magnets feeding EV/motor lines), gaussmeters, fluxmeters, Helmholtz coils, 3D field scanners, calibration. Complementary to Polymagnet rather than overlapping: Polymagnet/CMR makes programmed multipole magnets and the printing/magnetising around them, while Hirst is general-purpose magnetising + characterisation/QC. Acquiring Hirst would add (1) an 80+ year brand and standards credibility (CTO/CEO active in IEC/BSI/IOP magnetics standards), (2) PFM characterisation IP (SDFF/O2C) critical to rare-earth supply chains, (3) a recurring metrology/calibration product line, and (4) EV/automotive production-line relationships — the measurement + industrial-magnetising anchor of an equipment platform.
At the booth, operator-to-operator: "James, Tim Costello from Correlated Magnetics / Polymagnet — I've admired the PFM and SDFF work for years; you're measuring the exact high-coercivity materials our customers are trying to program. I'd love 15 minutes to compare notes on where magnetising and characterisation are heading for EV motor lines." Framed as two equipment-makers whose kit sits on the same production line — curiosity and complementary tech, not a buyer circling.
James — great to put a face to the PFM work at MMM; thanks for the time at the booth. At Correlated Magnetics we build the programmed-magnet and magnetising side, and your characterisation and metrology line is the piece that sits right next to ours on every serious motor program — which is exactly why I wanted to connect in person. I've been thinking a lot about how fragmented our corner of the industry is: a dozen excellent, independent equipment houses each solving one slice, when customers increasingly want the whole magnetise-measure-qualify chain to work as one system. I'm not pitching anything today — I'd just value a longer conversation about where you see Hirst heading and whether there are places our two platforms could pull in the same direction. If you're open to it, I'll come to you in Falmouth, or we grab an hour by video once the dust settles after Honolulu.
Excellent, mostly COMPLEMENTARY add to a "magnetizing-equipment platform." Polymagnet/Correlated Magnetics Research owns the "what" of magnetization — programmable, structured multipole (correlated / maxel) patterns; MAGSYS owns the "how and the proof": the pulse-power magnetizers, custom fixtures/coils, and the fluxmeter/gaussmeter/measuring-station metrology that actually impose and then verify a pattern. That makes MAGSYS both (a) a capability Tim's platform needs anyway and (b) a potential enabling supplier to Polymagnet's own patterning line. It also bolts on three scarce assets for a roll-up: German precision-engineering + FEM design talent, an established US channel with DoD/Navy magnetizing/measurement awards (NAICS 333618 / 334519 / 334513), and Asia reps (China, Singapore). Minimal product overlap/cannibalization with Polymagnet; the risk is that it's small and the ticket is modest.
Operator-to-operator, customer/partner framing — call or email James Murphy (NA sales): "James, it's Tim Costello at Polymagnet — Correlated Magnetics Research. We're one of the shops actually running pulse magnetizers and custom fixtures in anger to print our correlated multipole patterns, and MAGSYS keeps coming up as the team that does the magnetizing-and-measuring end better than almost anyone. I'd love to compare notes, engineer to engineer, on where magnetizing equipment is headed — no agenda beyond that." (No acquisition language in the first touch.)
Hi James — Tim Costello here, CEO of Polymagnet (Correlated Magnetics Research). I was at MMM in Honolulu this week and kept wishing MAGSYS had a booth across from ours — your modular magnetizers, custom fixtures and fluxmeters are exactly the kind of gear our programmable-magnet work lives and dies by, and I've admired how cleanly your team handles the magnetize-and-verify side. I've spent years convinced this industry is too fragmented for its own good, and I'm trying to build a home where the best magnetizing and metrology shops keep their own engineering identity and name while sharing a bigger commercial reach and a real US-defense channel. There's nothing to sign and no pitch — I'd just like to buy you a coffee or grab a Zoom to swap notes, and if Hartmut is ever open to it I'd value meeting him too; I'm happy to come to Dortmund. Even if a deal is the last thing on your minds, it'd be a pleasure to connect two shops that care this much about getting the magnetization right. — Tim
Near-anchor fit for an "Applied Materials of Magnetics" platform. Magnetic Instrumentation is a US-based (Indianapolis), 45+ year maker of the exact capital equipment and metrology the magnet industry runs on: magnetizers, custom magnetizing fixtures, and an accredited (A2LA/ISO 17025, NIST-traceable) calibration + testing lab, backed by 17+ magnetics engineers. It adds three legs a roll-up wants: (1) a broad magnetizer + custom-fixture product line, (2) recurring, sticky calibration/metrology services revenue, and (3) a deep magnetics engineering bench and a trusted 1979-era brand with an installed base across motor/automotive/medical/industrial magnet makers. Relationship to Polymagnet: COMPLEMENTARY, not competitive. Polymagnet/Correlated Magnetics sells programmable (multi-pole "maxel") magnet IP + printed magnets, which inherently depend on advanced magnetizing hardware and precise magnet metrology — MI is a leading supplier of precisely those magnetizers, fixtures and B-H/field-mapping QC tools. MI gives the platform the "pick-and-shovel" equipment + calibration layer beneath Polymagnet's design/IP layer, plus cross-sell into a shared customer base. Overlap is minimal (MI doesn't sell a competing programmable-magnet product); synergy is high.
Operator-to-operator, partner framing: "Tim Costello here — I run Polymagnet / Correlated Magnetics. For years our programmable-magnet work has leaned on the kind of magnetizers, custom fixtures and cal-lab rigor your Indianapolis shop is known for, and it struck me we've never actually compared notes. Could I grab 15-20 minutes to swap views on where custom magnetizing and magnet metrology are heading? You see a slice of the industry we don't, and vice versa." (No buyout language; positions Tim as a fellow magnetics operator and a natural customer/partner.)
Subject: Comparing notes — Polymagnet x Magnetic Instrumentation David — Tim Costello here; I run Polymagnet (Correlated Magnetics Research). For as long as we've been printing programmable magnets, our work has depended on exactly the things your Indianapolis team does best — solid magnetizers, smart custom fixtures, and metrology you can actually trust — and yet somehow you and I have never sat down together. I'd like to fix that. If you were out at MMM in Honolulu this week, I'm sorry we didn't connect on the floor; either way, could I steal 20 minutes by phone over the next couple of weeks? No agenda beyond comparing maps of where custom magnetizing and magnet testing are going — you've got 45 years of the industry's trust and a view I'd value, and I suspect there's a natural fit between what your shop builds and where we're trying to take the category. Happy to work around your calendar. — Tim
Adds the precision magnetic-field MEASUREMENT/metrology pillar to a magnetics-equipment roll-up. Near-zero product overlap with Polymagnet/Correlated Magnetics (programmable multipole magnet design + production) and strongly COMPLEMENTARY: Metrolab's HallinSight/MFC field cameras, THM/TFM probes and PM1055 reference magnets are exactly the QA, characterization and calibration tooling a programmable-magnet production line depends on. Its ISO 17025 lab makes it a de-facto standard-setter for how magnetic fields are measured, so owning it strengthens a platform's credibility across the whole value chain ("the company that defines how magnets are measured"). Bonus: the exclusive Kwan-tek deal gives the platform NV-diamond quantum-sensing optionality. Strategic fit is high; it is the metrology leg of an "Applied Materials of Magnetics."
Tim Costello here - I run Correlated Magnetics / Polymagnet over in the US, where we build programmable multipole magnets. Your teslameters and field cameras are the metrology we trust to characterize our fields, so after 40 years you've effectively set the standard for how precision magnetic fields get measured. I wanted to introduce myself as a fellow magnetics operator and swap notes on where this little corner of physics is heading - no pitch, just two people who care about the same hard problem.
Hi Thomas - Tim Costello here, CEO of Correlated Magnetics Research (we make the Polymagnet line of programmable magnets). Congratulations on 40 years, and on the Kwan-tek NV-diamond collaboration - pushing accurate measurement down to 1 mT below the NMR floor is a smart move, and that kind of measurement is exactly what our production lines live and die by. I've long thought the magnetics world is more fragmented than it should be: excellent specialist shops like yours and ours each solving one piece, with nobody tying the measurement, materials and magnet-design pieces into a single platform. I'd love 30 minutes, no agenda beyond comparing notes on where the industry could go if a few of us pulled in the same direction. I'm US-based and work closely with GMW on your side of the Atlantic, but I'm happy to come to Geneva - whatever's easiest for you.
Strong fit for a magnetics-EQUIPMENT platform — and a correction to the thesis. The believed "automotive magnet focus / West Coast" is only half right: West Coast (Morgan Hill/Silicon Valley) is confirmed, but the company brands itself to the "global high technology marketplace," not automotive (the automotive association most plausibly comes from Magcam field cameras being a staple of automotive/EV magnet QC — INFERENCE). What it actually adds is the "picks-and-shovels" rung Tim's roll-up wants: magnetizing equipment (magnetizers + fixtures), magnet metrology (hysteresisgraphs, Helmholtz coils, permeameters), and the Magcam magnetic-field-camera channel for North America, on top of vertically-integrated rare-earth/alnico/ferrite magnet + assembly supply. Complement to Polymagnet (Correlated Magnetics' programmable multipole magnets): magnetizing fixtures + Magcam field mapping are exactly the toolchain used to write and validate multipole patterns — genuine technical complement, with some metrology overlap. Net: a tuck-in that buys an equipment/metrology capability + a European instrument channel + a Silicon Valley footprint, not an automotive magnet volume play.
"I run Polymagnet — programmable multipole magnets — and honestly your magnetizing fixtures plus the Magcam field cameras are the exact toolchain we live or die on. I'd love to compare notes on where magnetizing and field-mapping are heading." (Partner/customer framing — the magnetizing + metrology toolchain — not an acquisition ask.)
Ron — good to see the magnetics crowd out in Honolulu for MMM this week; hope it was a good show. I run Correlated Magnetics (Polymagnet) — we design programmable multipole magnets, and the hardest part of our world is magnetizing them cleanly and then proving the field pattern is right, so your combination of custom magnetizing fixtures and the Magcam field-camera line is exactly the toolchain we and our customers lean on. I've wanted to compare notes with you for a while. I'm quietly pulling together a small group of people who build the picks-and-shovels of this industry — magnetizers, metrology, assembly — and I'd like to swap ideas on where it's all heading. No agenda beyond a good conversation: could we grab coffee or do a call the week after the show? Either way, nice work building something real out of Morgan Hill.
Adds the TEST & MEASUREMENT / metrology + QC pillar to a magnetics-equipment platform — arguably the most defensible, recurring-revenue layer (instruments + an accredited calibration-services annuity + a trusted 40+ country install base and brand). It is the global reference for characterizing soft-magnetic (electrical steel, EV-motor laminations) and permanent-magnet (NdFeB/SmCo/etc.) materials. Overlap with Polymagnet is minimal and the relationship is strongly COMPLEMENTARY: programmed/correlated-magnet and motor/sensor makers (Polymagnet's world) are natural Brockhaus customers, and Brockhaus-class metrology underpins Polymagnet QC. In an "Applied Materials of Magnetics" roll-up this is the metrology anchor sitting alongside magnet production/magnetizing/handling — a crown-jewel pillar, not a bolt-on.
"Stefan — for years Brockhaus has been the name our engineers trust to tell us the truth about what a magnet actually does. As we push programmed-magnet designs deeper into motors and sensors, metrology has moved to the center of our world, and I'd value 30 minutes to compare notes on where magnetic-materials testing is heading for EV and permanent magnets." (Partner/customer framing — a fellow engineering firm seeking to collaborate on metrology, not a buyer.)
Stefan — Tim Costello here, CEO of Polymagnet (Correlated Magnetics Research) down in Huntsville, Alabama. For years, Brockhaus has been the name our engineers trust when it comes to actually measuring what a magnet does, and as we push programmed- and correlated-magnet designs into motor and sensor applications, world-class metrology has become central to everything we ship. I just came out of MMM in Honolulu struck by how fast our corner of the world is converging — materials, measurement, and manufacturing all leaning on one another. I'd love to find 30 minutes to swap notes: where you see electrical-steel and permanent-magnet testing heading, and whether there's a natural way our two shops could help each other's customers. No agenda beyond building the relationship — I have real respect for what your family has built across generations in Lüdenscheid, and I suspect we're solving adjacent problems. If you're open to it, I'll happily work around your calendar, or start with your team in Alpharetta if that's easier.
Top-tier strategic fit for an "Applied Materials of Magnetics" platform. Bunting already covers three legs of the value chain Tim is assembling: magnet PRODUCTION (bonded NdFeB + precision assemblies via Magnet Applications/Bunting-DuBois), magnetic EQUIPMENT (separation, metal detection, magnetizing/magnetization systems), and DESIGN/engineering services — plus a global US+UK manufacturing footprint, distribution, and in-house magnet-materials R&D (Dr. Ormerod; 3D-printed NdFeB work with ORNL). Overlap with Polymagnet: both design and produce magnets and magnetic assemblies, so there is genuine product/engineering common ground rather than pure complement; Bunting adds industrial-scale equipment lines and channels Polymagnet lacks. IMPORTANT double-edge: Bunting is itself a serial consolidator (acquired Magnet Applications 2008, MagDev, Master Magnets 2017, Global Magnetics 2017) — i.e. a proven integrator and a competing roll-up player, so it reads more as a platform anchor / merger-of-equals / competitor than a simple tuck-in target.
"I run Polymagnet / Correlated Magnetics on the programmable-magnet side — I've admired what the Bunting family built across separation, materials, and assemblies for decades. I'm in the magnetics world for the long haul and trying to meet the people actually building it. Could we grab 20 minutes to compare notes on where the industry's heading?" (Peer/operator framing — no acquisition language.)
Hi Robert — Tim Costello here, from Polymagnet / Correlated Magnetics Research. First, my condolences on your father; Bob built something rare in this industry, and the fact that Bunting is still family-run three generations in says everything. I've spent my career on the programmable-magnet side, and I keep landing on the same thought: magnetics is a fragmented field full of great small shops, and the companies that figure out how to work together will own the next decade. Bunting has done that better than almost anyone — materials, separation, metal detection, assemblies, US and UK under one roof. I'd genuinely just like to get to know you and swap views on where it's all going; no agenda beyond that. If you or your materials team happen to be around MMM in Honolulu this week I'd love to say hello, otherwise a call whenever suits. Either way, glad we're in the same business. — Tim
Strong, clean complement to a Polymagnet/CMR equipment platform. CMR's strength is programmable/correlated magnets plus magnetizing and printing systems; Group3 supplies the metrology leg — calibrated Hall-effect teslameters and probes that map, characterize and QC magnetic fields, the measurement step adjacent to any magnetizing operation. Minimal product overlap (CMR doesn't make precision field meters), high adjacency. A roll-up gains a 40-year trusted instrument brand, a global lab install base (CERN/SLAC/ANSTO/Argonne/ORNL per their stated client list), a semiconductor ion-implantation control-module line, ISO 9001:2015, and fresh US + European (Caylar) distribution to cross-sell through. Textbook bolt-on for the "Applied Materials of Magnetics" thesis — the measurement/instrumentation vertical.
Customer-and-peer framing, zero acquisition talk: "Group3 teslameters have been the quiet standard on magnet benches for 40 years — ours included. With programmable and correlated magnets scaling up, I'd love to compare notes on where precision field measurement is heading, and where our roadmaps might help each other commercially." It leads with genuine respect + a shared technical future, and opens a partnership/cross-sell door rather than a sale.
Hi [name] — good to be in the same orbit around MMM in Honolulu this week. I run Correlated Magnetics Research — the Polymagnet team — down in Huntsville, and I'll admit this note is overdue: Group3 teslameters and Hall probes have been on our benches for years, so I've been a quiet customer of yours for a long time. We're building out a broader magnetics-equipment platform — magnetizing, printing and characterization under one roof — and I keep coming back to how respected Group3's precision measurement work is, especially now with your new US presence and the Caylar tie-up. I'd love to grab 30 minutes after the show, operator to operator, to swap notes on where field measurement is going as programmable magnets go mainstream and to see whether our roadmaps could pull some weight for each other commercially. No agenda beyond a good conversation. Either way, glad our paths crossed this week. — Tim
Cornerstone-grade. LE adds the production magnetizing + magnetic-measurement + inline-QC + automation layer to a magnetics-equipment platform — the hardware that charges magnets at volume and proves they're right. That complements Polymagnet/CMR's programmable/correlated-magnet IP (the field patterns) rather than competing with it: CMR designs the magnetization; LE builds the stations that apply and verify it on an automotive line. Overlap is only partial (both touch "magnetizing equipment"), but LE is far broader in measurement, automation, global service (US/China/Vietnam) and customer reach (2,000+ clients, Foxconn/automotive relationships). For an "Applied Materials of Magnetics" roll-up this is a keystone equipment acquisition that instantly adds measurement + QC breadth and a global install/service base.
"Andrea — I've followed your fourth-generation magnetizing stations and the inline QC work for e-mobility rotors, and it strikes me we sit at opposite ends of the same value chain: at Polymagnet we design the magnetization patterns, and Laboratorio Elettrofisico builds the stations that apply and verify them at production scale. I'd love to compare notes on where our automotive and consumer-electronics customers overlap, and where your magnetizers and our programmable fields might do more together." (Partner/customer framing — curiosity and complementarity, no ownership talk.)
Hi Andrea — Tim Costello here, CEO of Polymagnet (Correlated Magnetics Research) in Huntsville. I've admired Laboratorio Elettrofisico for years — your fourth-gen magnetizing stations and inline magnetic QC are exactly the production-and-measurement backbone that programmable magnets like ours need to reach real volume, and congratulations on the Foxconn recognition this year; that's hard-earned. We're not competitors — we live at opposite ends of the same chain: we design the field patterns, you charge and verify them at scale — and I think there's real pull for our shared automotive and consumer-electronics customers if we put the two together. I'd welcome a low-key call just to trade notes on the e-mobility roadmaps we're both chasing, with no agenda beyond getting to know your team. If it's easier to start stateside, I'm happy to say hello to Jacob in Lake Orion first since we're both this side of the Atlantic. Either way, I'd enjoy the conversation.
Strong, clean tuck-in for a magnetics-EQUIPMENT platform. Oersted adds (1) a US-made pulse/capacitor-discharge magnetizer product line, (2) genuine custom magnetizing-fixture design know-how, (3) a magnetic-metrology instrument line (gaussmeters, fluxmeters, Helmholtz coils) useful for QA across a roll-up, and (4) deep documented domain expertise (Stupak's magnetizing methods are widely cited). Relative to Polymagnet / Correlated Magnetics Research — which PROGRAMS structured multipole "maxel" fields and builds the printing systems to do it — Oersted is complementary, not redundant: Polymagnet prints programmable fields; Oersted is conventional impulse-magnetizing hardware + fixtures + measurement. Together they span "magnetize any geometry, conventional or programmed, and verify it." Caveat: because the company looks dormant (see approachability), realistically this is an ASSET pickup — brand, fixture/magnetizer designs, customer list, instrument IP, and Stupak/Stere's know-how — not the purchase of a staffed, revenue-generating operating company. The core ECS patent is expired, so the moat is brand + designs + know-how, not live patents.
Lead as an admirer and fellow operator, not a buyer: "I was just at MMM in Honolulu and found myself wishing you'd been there — I've had your 'Methods of Magnetizing Permanent Magnets' on my bench for years, and your ECS magnetizers shaped how a lot of us think about capacitor-discharge work." Then ask, operator to operator, whether he's still doing custom fixture and prototype magnetizing, and how he sees the future of the shop — framed as wanting to keep that know-how in play, never as an offer.
Joe — Tim Costello here, from Correlated Magnetics Research; we make the Polymagnet programmable magnets down in Huntsville. I've had your "Methods of Magnetizing Permanent Magnets" open on my bench for years — it's still the clearest thing anyone's written on impulse magnetizing and fixture design, and your ECS magnetizers taught a lot of us how to think about capacitor-discharge work. I was in Honolulu this week for MMM and kept wishing I'd had the chance to shake your hand. We're quietly pulling together a group of the best small magnetics-equipment shops in the country — the magnetizer, fixture and measurement specialists the big players never bothered to build — and I'd love to compare notes on where Oersted's work stands today and whether there's a way to keep that craft in play. No agenda beyond a good conversation between two people who care about this corner of the industry — could I call you next week? (Tim will sign.)
