What 603 MANUFACTURING does

603 Manufacturing is a private US contract manufacturer founded in 1998 and headquartered at 46 River Road, Hudson, New Hampshire, operating as a subsidiary of Trexon (previously affiliated with RF Logic). The company specializes in custom cable assemblies and electro-mechanical assemblies, with core capabilities spanning wire harnesses, RF cables, potted cable assemblies, ribbon cables, box builds, system integrations, rack panel assemblies, DIN rail assemblies, and configured-to-order product assembly. Manufacturing relies on specialized equipment including Pines M54556 bending machines for semi-rigid cable forming and Schleuniger SR1000 cable strippers, supported by in-house mold capabilities using UL 94V-0 rated compounds, hot-stamping wire marking, and 100% continuity testing.

The company serves five primary verticals — Defense/Military, Aerospace/Space, Medical, Industrial, and Commercial — with notable certifications including AS9100D (certificate 0073511-02), NASA 8739.X approval, ISO 9001:2008, ITAR compliance, DFARS flow-down documentation, RoHS compliance, and UL/CSA certifications. A dual manufacturing footprint combines a domestic facility in Hudson, NH with offshore production locations, enabling quick-turn domestic prototyping alongside cost-competitive higher-volume offshore runs. Engineering services include New Product Introduction, Design for Manufacturability, prototyping, and on-site testing.

Revenue is generated through project-based B2B contract manufacturing, with quoting handled via direct phone (603.578.9876 / 603.881.8336) and email ([email protected]). The company distributes primarily through a sales-led motion with a relationship-driven enterprise channel, supplemented by an online RF Cable Builder tool for self-service configuration of standardized RF cable orders. No public pricing tiers, revenue figures, named customers, or management team are disclosed in available sources.
