Our custom injection molding locks in all five, with moulds built from P20, 718, 738, NAK80, and S136 steels so every dimension and surface stays true through the whole run. Color is matched to your standard, hardness tuned to the application, and your logo molded or embossed cleanly into every piece. Give us your specifications, and we will turn them into production-ready parts.
