Plastic mould steel is the core material for injection molds, compression molds, blow molds, and mold bases used to mass-produce plastic components. As a professional manufacturer and supplier in China, ShengHe Metal supplies key steel grades such as P20, 1.2311, 1.2738, 1.2083, 1.2316, and more, available as round bars and blocks. Our material is produced via Electric Arc Furnace (EAF) steelmaking (ESR remelting also available), ensuring high purity and a homogeneous structure. This results in exceptional polishability for glossy parts, superior wear resistance for long production runs, and a low possibility of porosity and inconsistent hardness. Our capability to produce large-size round bars and blocks also supports larger mold bases and mold cavities, ultimately giving you longer mold life, reduced maintenance, and consistent part quality.
Choosing the right plastic mould steel directly affects mold lifespan, product surface finish, and production efficiency. ShengHe Metal stands out as a trusted China-based supplier due to its integrated forging, heat treatment, and machining capabilities. With strict Quality Control Procedures, every batch meets international standards. Our ready stock of over 3,000 tons ensures fast delivery for urgent projects. Additionally, we provide customized processing services to meet specific industrial requirements. If you are looking for a reliable plastic mould steel manufacturer in China, ShengHe is your ideal partner.
