Our plastic mold division designs and manufactures high-quality injection molds for diverse industrial applications. With advanced CAD/CAM/CAE engineering capabilities, we optimize mold design for manufacturability, cycle time, and part quality. Our molds serve the automotive, medical, consumer electronics, home appliances, and industrial equipment sectors. We offer single-cavity and multi-cavity molds with hot-runner or cold-runner systems, tailored to your production volume and precision requirements.
Auto spare parts is the unit of the whole auto parts processing and the products serving the auto parts processing.
Plastic Molds: Rainbowmold supplies the Plastic Molds together with the matching injection tooling, engineering single- and multi-cavity molds with hot-runner or cold-runner systems, conformal cooling and optimized gating for cycle-time and part-quality targets. mold steels include P20, 718H, H13, NAK80 and S136 hardened to the required HRC; rated for long-run mass production up to one million cycles. DFM and Moldflow analysis are provided before cutting steel, and CNC, EDM and wire-cut machining with SPI-standard polishing hold cavity accuracy. Dimensional part tolerance can reach +/-0.01mm. Production serves automotive interior & exterior parts, electronics housings and medical consumables, and all work is run under an ISO 9001 / ISO 14001 quality system. Send us your 3D STEP or IGES model for a free DFM report and mold quotation within 24-48 hours.
