We analyze your design for manufacturability — wall thickness, draft angles, gate locations — before cutting any steel.
Simulation of resin flow, weld lines, and shrinkage to optimize gate position and cavity layout for perfect parts.
General arrangement drawings confirmed with customer before mold machining begins — zero surprises downstream.
CNC machining, EDM, and grinding to build the mold. Hardened steel cavities for long-run production durability.
First-off trial with full dimensional report. We iterate until every dimension hits spec — then ship samples for your approval.
Mass production with 100% inspection. CMM reports, material certs, and on-time delivery — every time.
From your drawing to finished parts — fast, transparent, and hassle-free.
