Custom Plastic Injection Mould with P20/718/738/NAK80/S136 Mould Material and 250000-300000shots Mould Life

When you compare injection molding suppliers, the steel behind the mold decides the outcome. With P20, 718, 738, NAK80, and S136 mould materials, our customized plastic injection molding balances upfront cost, machinability, and long-run durability. Complex parts come out with sharp details and stable dimensions, while hardened grades like NAK80 and S136 handle abrasive or high-polish applications with ease. That combination is what makes us your best option for reliable, repeatable production.
