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.
