What are the classifications of mold steel by usage

1. Cold work die steel

Cold work die steel is mainly used to manufacture molds for press forming of workpieces under cold conditions. Such as: cold punching die, cold stamping die, cold deep drawing die, embossing die, cold extrusion die, thread pressing die and powder pressing die. The range of cold work die steel is very wide, from various carbon tool steel, alloy tool steel, high speed tool steel to powder high speed tool steel and powder high alloy mold steel.

2. Hot work die steel

Hot work die steel is mainly used to manufacture molds for pressure processing of workpieces under high temperature conditions. Such as: hot forging dies, hot extrusion dies, die casting dies, hot upset dies, etc. Commonly used hot work die steels are: medium and high carbon alloy die steel with CR, W, MO, V and other alloy elements added; for special requirements of hot work die steel, sometimes high alloy austenitic heat resistant die steel is used .

3. Plastic mold steel

Because of the many varieties of plastic, the requirements for plastic products are also very different, and various functional requirements are also put forward for the materials used to make plastic molds. Therefore, many industries have developed a wide range of plastic mold steel series. Including carbon structural steel, carburized plastic mold steel, pre-hardened plastic mold steel, age hardening plastic mold steel, corrosion-resistant plastic mold steel, easy-cut plastic mold steel, integrally hardened plastic mold steel, martensite Aging steel and plastic mold steel for mirror polishing.
