Cold working die
Cold working die steel is mainly used in the manufacture of cold state of the workpiece for the press molding mold. Such as: cold blanking die, cold stamping die, cold deep-drawing die, embossing die, cold extrusion die, thread pressing die and powder pressing die. Cold work die steel has a wide range, . From a variety of carbon tool steel, alloy tool steel, high-speed tool steel to powder high-speed tool steel and powder high-alloy die steel. Cold work die steel is vacuum degassing refined steel, pure internal quality, good machinability, cutting significantly improved, good hardenability, air-cooled quenching hardening is not easy to appear quenching cracks, wear resistance is extremely excellent, good toughness, can be used as a stainless steel and high hardness materials punching die.
Hot work mold
Hot work die steel is mainly used to manufacture the high temperature state of the workpiece pressure processing mold. Such as: hot forging mold, hot extrusion mold, die casting mold, hot heading forging mold. Commonly used hot work die steel: high carbon content in the addition of Cr, W, Mo, V and other alloying elements of alloy die steel; for special requirements of hot work die steel, sometimes using high alloy austenitic heat-resistant die steel manufacturing.
Plastic mold
Because of the many varieties of plastics, plastic products, the requirements of the difference is also very large, the material for the manufacture of plastic molds also put forward a variety of different performance requirements. Therefore, many industrially developed countries have formed a wide range of plastic mold steel series. Including carbon structural steel, carburizing plastic mold steel, pre-hardened plastic mold steel, age-hardened plastic mold steel, corrosion-resistant plastic mold steel, easy to cut plastic mold steel, the whole hardened plastic mold steel, martensitic aging steel, and mirror polishing with plastic mold steel.
