Basic Information

XPM Plastic mould steel
Product Overview
XPM Plastic Mould Steel is a premium, chromium-manganese-nickel-molybdenum alloyed steel, specifically engineered for large and medium-sized plastic injection moulds. Delivered in a pre-hardened condition (38-42 HRC or 34-38 HRC depending on variant), XPM Plastic Mould Steel offers a superior combination of high thermal conductivity, excellent machinability, and uniform through-hardening properties. It is the industry’s top choice for manufacturing high-quality automotive components, large household appliances, and complex electronic housings where surface perfection and dimensional stability are paramount.
