Protomatic

What Protomatic does

Protomatic is a precision CNC machining and contract manufacturer headquartered in Dexter, Michigan, founded in 1971 and operating from a single facility at 2125 Bishop Circle West. The company runs 3-5 axis milling and 2-8 axis turning for prototype and short-run production of small-to-medium complex components, serving mission-critical applications in medical (orthopedic, cardiovascular, dental, optical, surgical instruments), aerospace (commercial, military, satellites, space vehicles), defense (ITAR-registered land, air, naval, and space platforms), and automotive (OEM and vintage restoration) industries. It employs 101-250 staff, is privately held by the Wetzel family, and holds a rare combination of ISO 9001:2015, ISO 13485:2016, and AS9100D:2016 certifications.

The core technology stack combines subtractive CNC machining with rare hybrid additive/subtractive capability: Protomatic was the first US installer of the SPEE3D LightSPEE3D cold-spray 3D metal printing system in 2018, enabling near-net-shape builds refined by precision milling. Supporting capabilities include ceramic tooling for nickel-based superalloys, advanced toolpath optimization (VoluMill, TruMill), frequency-analysis vibration detection (Harmonizer), and a broad inspection suite (CMM, Keyence super-resolution microscope, Taylor-Hobson Form Talysurf, Nikon VMC-3020 vision, laser micrometers). The shop is qualified and approved by named OEMs including Ford, General Dynamics, SpaceX, Blue Origin, Boeing platform programs, Sparton Defense Electronics, Cadillac, and Rolls-Royce.

Protomatic makes money as a custom job-shop: revenue is generated quote-by-quote based on material, complexity, tolerances, and volume, with no disclosed subscription or recurring model beyond a small GD&T training revenue stream ($650/person, two-day courses run with M and M Consulting). Go-to-market is sales-led, with inside-sales representatives preparing detailed quotes triggered by website forms, phone, and email; field sales support key accounts. Distribution is domestic-only (single country, North America/USA). Operating since 1971, the company has run continuous ERP systems (E2 Shoptech since 1999, JobBOSS² since 2026), maintains a 96.45% on-time-delivery KPI, and reports over 700 different parts manufactured for spaceships and satellites. No external funding, M&A, or public-market activity is recorded.
