The performance of plastic mold steel

The performance of plastic mold steel requires plastic products to be molded by injection (injection), compression (compression molding), extrusion, injection, and blow molding. The plastic mold components are divided into two categories. One type is structural parts, including gating system, guide parts, fixed formwork, ejector mechanism parts, support parts, etc. The selected materials are generally medium and low carbon carbon structural steel or alloy structural steel and carbon tool steel. Standard products are available in the parts market; the other type is molded parts, including cavities, cores, inserts, etc., which are the key components of directly molded plastic products. The structure of the molded part is complex, the size of the fine sulfur joint is required to be close and the surface is smooth. Although the strength and toughness required by the material are not as high as the cold work mold and the hot work mold, it must have specific performance requirements.
