Forest City Manufacturing Drives Precision Equipment Production
Rockford's industrial equipment sector is powered by the region's deep roots in aerospace fasteners, machine tools, and precision manufacturing. Collins Aerospace (RTX) in Rockford machines hydraulic and pneumatic components for aerospace with direct application to industrial equipment. Woodward Inc. manufactures control systems for turbines, compressors, and industrial engines. Ingersoll Machine Tools (now Camozzi) built Rockford's precision manufacturing reputation, and the metro's dense network of machine shops produces pump housings, valve bodies, and gear components for industrial OEMs nationwide.
RivCut machines industrial equipment components for Rockford-area OEMs — valve trim, pump impellers, turbine fittings, and gearbox housings — with the precision Rockford's world-class manufacturing corridor demands.
