P40 plastic mold steel plate is an advanced, heavy-duty pre-hardened tool steel tailored explicitly for extra-large and complex plastic injection molds that demand higher core strength than standard P20 variants. Supplied by KUTU at a precise pre-hardened state of 36-40 HRC, our P40 plastic mold steel plate delivers high impact toughness, superior yield strength, and remarkable resistance to high-injection pressures, preventing mold cracking or wall deflection during long-run production.
It is highly recommended for manufacturing deep-cavity automotive bumpers, large waste bins, and industrial crates. KUTU utilizes strict electro-slag remelting (ESR) or vacuum degassed processes to guarantee that the P40 plastic mold steel plate maintains consistent polishing and texture replication characteristics across massive dimensions, giving international molders the ultimate reliability and structural wear resistance needed for high-speed automated production.
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.
