EV-Grade Materials
Aluminum 6061/7075 and 316L stainless with material certs.
Sealing Precision
±0.0005" on o-ring grooves and sealing flanges.
QC Docs
CMM inspection reports on every EV battery component order.
Midwest Manufacturing Hub for Auto Assembly and Supply
Chicago's automotive footprint includes Ford's Chicago Assembly Plant building the Explorer and Lincoln Aviator, the Stellantis Belvidere complex to the west, and a dense corridor of Tier 1 and Tier 2 stamping, machining, and plastics suppliers stretching from the South Side to Joliet. Magna International, Martinrea, and ZF Friedrichshafen all operate major Chicagoland facilities.
RivCut serves Chicago-area auto suppliers with fast-turn CNC machining, tight-tolerance production runs, and the PPAP documentation your OEM quality system requires.
