CNC Machining Prototype Service Aluminum: Rainbowmold machines the CNC Machining Prototype Service Aluminum as a custom CNC part directly from your 3D model. we use multi-axis machining centers, CNC lathes, mill-turn centers, Swiss machines and EDM for complex one-piece parts. materials machined include aluminum, alloy & stainless steel, brass, copper, titanium and engineering plastics. we hold critical features to +/-0.005mm and polish surfaces to Ra 0.2-0.4; post-machining services include anodizing, plating, passivation, heat treatment and precision grinding. Parts are inspected on a CMM with full dimensional and material reports before shipment. aerospace, medical, automotive, robotics and precision-instrument programs programs are supported under an ISO 9001 quality system for prototype, low-volume and serial production.
