Paramount Machine Company

What Paramount Machine Company does

Paramount Machine Company, Inc. is a privately held, family-owned precision machining firm founded in 1979 and headquartered in Manchester, Connecticut. The company operates three Manchester-area facilities totaling more than 80,000 square feet of production space and manufactures close-tolerance components and assemblies for the aerospace and defense industries, including housing assemblies, impellers, turbine nozzles, compressor housings, shafts, and a portfolio of more than 10,000 different part numbers.

Its manufacturing technology stack centers on multi-axis CNC machining (Matsuura five-axis and Haas/Mitsui Seiki mills), CNC turning up to 20 inches in diameter on Okuma, Eurotech, Star, Nakamura, Hitachi Seiki and Hwacheon platforms, wire and die-sink EDM (Fanuc RoboCut, Agie Charmilles), ID/OD and surface grinding (Kellenberger, Okamoto, Studer), and NADCAP-accredited heat treatment, passivation, nital etch, and non-destructive testing (magnetic particle and fluorescent penetrant inspection). Inspection is supported by Hexagon and Sheffield CMMs, optical comparators, and Tesa Micro-Hite measurement. A dedicated engineering department provides CAD-based manufacturing and reverse-engineering from prints or IGES/DXF files, with ERP and tablet-based scheduling used for shop-floor control.

The business model is contract manufacturing under AS9100D and ISO 9001:2015 quality systems, with NADCAP accreditation and DFARS and NIST SP 800-171 compliance supporting work for Collins Aerospace, Pratt & Whitney, Sikorsky, Raytheon, Safran, Parker Meggitt, DLA, USAF, and DOD. Pricing is fully quote-based with multi-year contract structures, and customer acquisition runs through direct enterprise field sales plus industry reputation rather than third-party distribution or marketing channels.
