In mold processing, because of the wide range of applications of molds, the working conditions of different molds are very different, so the range of materials used to make molds is very wide, the most widely used mold material is cast steel. From ordinary carbon structural steel, carbon tool steel, alloy structural steel, alloy tool steel, spring steel, high-speed tool steel, stainless steel heat-resistant steel to martensitic aging steel and powder high-speed steel to meet the needs of special molds and powders. High alloy die steel, etc. Mold steel can generally be divided into three categories: cold work mold steel, hot work mold steel and plastic mold steel.

Cold Work Steel

Cold work tool steel is mainly used for manufacturing cold press forming as blank tooling. Such as: cold punching die, cold forming die, cold drawing die, embossing die, cold extrusion die, thread pressing die, powder pressing die, etc.. The range of cold work tool steel is wide: from various carbon tool steel, alloy tool steel, high speed steel to powder high speed steel and powder high alloy tool steel.

Stamping steel for hot working

Hot work tool steel is mainly used for making dies for high temperature stamping workpieces. Such as: hot stamping dies, hot extrusion dies, injection moulds, hot upsetting dies, etc. Commonly used hot stamping die steel are: add alloying elements of medium and high carbon alloy die steel, such as Cr, W, Mo , V; for special requirements of hot forging die steel, using high alloy austenitic heat-resistant die steel is sometimes used.
