S136 S136H Corrosion Resistant Stainless Plastic Mould Steel Plate for PVC and Transparent Product Moulds

S136 and S136H stainless plastic mould steel plate are premium corrosion-resistant mould materials widely used in the production of transparent plastic products, medical devices, PVC components, and humid-environment moulds. The high chromium content in S136 stainless plastic mould steel plate provides outstanding rust and corrosion resistance, preventing mould deterioration when processing acidic or corrosive plastics such as PVC, PET, and PU. This material also delivers exceptional mirror polishing performance, enabling the production of crystal-clear transparent products with no flow marks or imperfections, making S136 stainless plastic mould steel plate essential for high-end optical and packaging moulds.
Our S136 stainless plastic mould steel plate is manufactured through advanced smelting and refining processes to ensure high purity, uniform structure, and excellent hardenability. S136H is supplied in a pre-hardened condition for direct machining, while S136 can be quenched to achieve higher hardness and wear resistance based on production requirements. Both grades offer exceptional dimensional stability during heat treatment and machining, minimizing deformation and ensuring long-term precision of mould components. The stainless structure also simplifies maintenance, as the mould is less likely to rust during storage or intermittent production.
In practical applications, S136 stainless plastic mould steel plate is widely used for manufacturing moulds for lenses, syringes, cosmetic bottles, and transparent electronic components. Its excellent wear resistance extends mould life significantly, reducing production downtime and maintenance costs. We offer thickness options from 10mm to 200mm and provide customized cutting, precision grinding, and pre-heat treatment services. Whether you choose S136 or S136H stainless plastic mould steel plate, you benefit from superior corrosion resistance, polishing performance, and durability, ensuring high-quality output and reliable performance for demanding plastic moulding applications.
