FT64 plastic mold steel plate is a premium-grade, pre-hardened martensitic stainless mold steel meticulously engineered for industries requiring exceptional surface finish and high-end polishing performance. At KUTU, our FT64 plastic mold steel plate undergoes strict vacuum degassing and refined forging processes to eliminate internal micro-defects, making it particularly suitable for optical parts, high-precision electronic connectors, and luxury cosmetic packaging molds where flawless surface quality is non-negotiable.

With its outstanding chromium alloy balance, this steel grade delivers supreme corrosion resistance against aggressive plastics like PVC, while maintaining excellent dimensional stability during high-volume injection molding cycles. By choosing KUTU’s FT64 plastic mold steel plate, global mold manufacturers can achieve mirror polishing up to #10000 grit without pits or inclusions, significantly extending tool lifespan and decreasing maintenance overhead in high-pressure manufacturing environments.
