P20M plastic mold steel round bar is an upgraded chromium-manganese-molybdenum alloy steel delivered in a uniform pre-hardened condition (typically 28-32 HRC). KUTU supplies high-density P20M plastic mold steel round bar specifically optimized for manufacturing structural components, ejector pins, mold bases, and core bars in plastic injection molding. The uniform hardness throughout the entire cross-section guarantees isotropic mechanical properties, ensuring zero soft spots even in large diameter bars.
This versatile steel grade offers brilliant machinability, allowing precision machine shops to perform high-speed milling, drilling, and EDM without the risk of post-machining deformation. Our P20M plastic mold steel round bar is the cost-effective industry standard for large and medium-sized plastic molds, providing reliable structural integrity and high wear resistance for automotive interior molds and home appliance toolings.
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.
