S136 plastic mold steel plate (including the S136H pre-hardened variant) is a premium-grade martensitic stainless mold steel renowned for its exceptional corrosion resistance and world-class mirror polishing capabilities. At KUTU, our S136 plastic mold steel plate undergoes advanced electro-slag remelting (ESR) to ensure a highly pure chemical microstructure. This makes it the ultimate choice for manufacturing high-precision medical packaging, optical lenses, and transparent consumer electronics molds that demand zero surface imperfections.
Formulated with a high chromium content, S136 plastic mold steel plate provides robust protection against chemically aggressive plastics like PVC and recycled polymers, effectively preventing rust inside cooling channels. KUTU’s rigorous ultrasonic testing guarantees an incredibly homogeneous material with uniform hardness from core to surface. By implementing our S136 steel blocks, mold makers can achieve a flawless mirror finish up to #10000 grit, ensuring long-term structural integrity and minimizing costly factory maintenance downtime.
A：Absolutely. Beyond supplying raw materials, we provide full custom precision machining services. This includes CNC milling, grinding, surface flattening, and custom vacuum heat treatment tailored to your exact blueprints. We deliver near-net-shape blocks to save your production time.
A：Yes, our facility is equipped with heavy-duty CNC milling machines, high-precision grinding machines, and automated sawing systems. We supply not only raw tool steel plates but also fully machined mold bases and custom-sized steel blocks according to your industrial specifications.
A: Our comprehensive service covers everything from steel grade selection consulting to custom cutting, precision machining, and full internal ultrasonic testing (SEP 1921-84). This ensures global toolmakers receive ready-to-use materials with guaranteed quality.
A： Yes, absolutely. We understand that tool and mold steel reliability is critical to your tooling life and production stability. We provide free material samples (standard test blocks or small discs) for metallurgical analysis, chemical composition testing, and hardness verification. You can place a sample request via our chat or contact forms.
A： While the steel material itself is 100% free, international express freight (via DHL, FedEx, or UPS) is typically covered by the buyer. You can provide your courier account number for freight collect. Our Premium Policy: The exact shipping cost you paid for the sample will be 100% credited back and deducted from your first bulk trial order invoice, making the entire sample process completely risk-free for you.
