Dexter Magnetic Technologies / MCE (Magnetic Component Engineering) — part of Permag

Magnet machining, magnetizing, and assembly, drawing on raw magnet material (including EEC's samarium-cobalt) rather than producing raw magnet alloy or material themselves.

Capacity

This company machines and assembles magnet blocks made elsewhere rather than pressing or sintering its own. Capacity in that work is set by what customers ask for in a given period rather than by installed press or furnace capacity, so it moves with the job mix. A single tonnage figure would describe one quarter's order book and misrepresent every other one. There is no figure here because there is no figure that would mean anything, not because one is being held back.

Narrative

Dexter Magnetic Technologies and MCE (Magnetic Component Engineering) are two historically separate companies now combined under one private-equity-backed parent and marketed under the "Permag" brand. Dexter Magnetic Technologies was founded in 1951 in Elk Grove Village, Illinois. MCE was founded independently in Torrance, California, and was acquired by Dexter Magnetic Holdings in March 2022. The Permag brand, which also includes Electron Energy Corporation (EEC), was publicly launched in June 2025. Unlike EEC, which produces raw samarium-cobalt magnet material, Dexter and MCE focus on machining, magnetizing, and assembling finished magnetic components and assemblies; no public production-tonnage or throughput figures were found for either company, consistent with a finishing and assembly business model rather than raw-material production.

How this page is sourced

Everything here comes from public sources — company filings, annual reports, exchange announcements, government releases and trade press. Every figure is linked to the document it came from and carries the date that document was published, because a capacity number without a date is not a fact, it is a rumor with a decimal point.

What is deliberately absent: material nonpublic information. I have spent more than two decades in this industry and a good deal of what I know about these companies I learned under NDA. Those obligations do not expire and they do not bend for a website. Nothing I have been told in confidence appears here in any form, and nothing on this page — or missing from it — should be read as a signal about what I know privately. I hold NDAs absolutely. It is the reason clients tell me things.

Judgment is the other thing left out on purpose. This page reports what has been published and who published it. Whether a target is credible, whether a ramp will hold, whether a capacity figure survives contact with the plant behind it — that is the work I do for clients, and it does not belong in a free reference page.

Where public sources disagree, I say so rather than picking a winner. Where a figure has not been published, the field says so rather than carrying an estimate. An empty field is information too.

Public filings tell you what a company has said. Whether it holds up is a different question, and the one I get hired to answer.
