What MGAI does

MGAI is a privately held French precision machining job shop established in 1977 and headquartered in Chanas, France, operating from a single 2,500 m² industrial workshop on the RN7 corridor. The company specializes in CNC machining of small, medium, and large-dimension mechanical parts from unit pieces through small series, together with mechanically-welded assembly fabrication. Its machine park spans CNC vertical and horizontal turning (up to Ø4,000 on a Berthiez with Siemens 840D), large CNC boring and milling (Heidenhain-controlled, up to 4,200 x 1,250 x 1,500 mm), and large-dimension machining centers with 10-tonne lifting capacity, supported by in-house metrology (Mahr profilometer, COFRAC-approved 3D measurement, dedicated NDT zone) and CAD/CAM (SolidConcept, AutoCAD 2015, ZW CAD 3D) linked to a PMI SOFT Cegid ERP/GPAO system. A distinctive capability is machining of exotic alloys including Inconel, applied to heavy industrial components such as winch drums with bearing and gearmotor assemblies, gearbox housings, and nuclear-grade valve bodies, with in-house secure packaging and specialized transport for oversized workpieces.

The business model is project-based contract manufacturing sold directly to enterprise customers through relationship-led sales, project quotation, and customer references (displayed on the company website). MGAI is ISO 9001:2015 certified (certificate 457074/r1 by APAVE) and is actively pursuing ISO 19443 certification to formalize its standing in the French nuclear supply chain. The customer base is concentrated in the French nuclear sector, with EDF, Orano, Arabelle Solutions, and SDMS as named enterprise clients, alongside other heavy-industry OEMs; revenue mechanics are anchored in custom part pricing tied to material, tolerance, and volume specifications.

The company is privately held with no disclosed funding rounds, no parent organization, and no headcount data beyond a stated range of 11–50 employees. Operating geographies are limited to France/Europe, served exclusively via direct industrial sales rather than distribution or digital channels; no app, API, or software product surface exists beyond a marketing website and contact forms.
