Multi-Cavity High-Shot-Count Production Mold

Multi-Cavity High-Volume Production Injection Molds: Rainbowmold designs and builds high-cavity-count production tooling for caps, closures, connectors, fasteners and small precision components running millions of shots. We balance multi-cavity hot-runner networks for consistent part weight, use hardened and coated wear parts for tool life, and add conformal cooling to shorten cycle time. With 20+ years of experience and CNC EDM grinding capability, we optimize each mold for productivity and dimensional stability.

 Multi-Cavity High-Shot-Count Production Mold: Rainbowmold supplies the Multi-Cavity High-Shot-Count Production Mold 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 industrial, electronics, personal-care and automotive component projects, 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.
