Our Custom Plastic parts Capabilities

High-volume molding & agile CNC solutions for prototypes to mass production your content goes here

plastic injection molding

Ideal for high-volume runs (1,000+ units) with complex geometries. High upfront tooling costs offset by low per-part pricing and fast cycle times. Best for final products.

plastic cnc machining

Perfect for prototypes & small batches (1-500 units). No molds needed – faster setup, higher design flexibility, but higher per-unit costs. Ideal for testing or low-volume custom parts.

Urethane Casting

Vacuum Casting with RJCmold means you get quick production of high quality, reproducible parts with PLC control at a lower cost,
all with a highly efficient shots per mold (from 1-500 parts).
