718H plastic mold steel plate is a vacuum-melted, pre-hardened chromium-nickel-molybdenum alloy steel that represents the pinnacle of performance for large-scale high-gloss injection tools. KUTU’s premium 718H plastic mold steel plate is supplied at a hardened range of 33-38 HRC, completely eliminating the risks, costs, and time associated with post-machining heat treatment. It features vastly superior cleanliness and a finer grain structure compared to standard P20 grades.
Engineered specifically for high-gloss automotive dashboards, large electronic housings, and premium consumer goods, our 718H plastic mold steel plate offers extraordinary texturing and photo-etching capabilities. The deliberate nickel addition guarantees excellent core toughness and uniform hardness from the plate surface down to the deep core, allowing global tooling factories to achieve mirror-like finishes and optimal thermal conductivity during rapid cooling cycles.
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.
