Die steel is a type of steel used to make cold stamping dies, hot forging dies, die casting dies and other dies. Dies are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the die directly affects the quality of the pressure processing process, the precision output of the product and the production cost. The quality and service life of the die are mainly affected by the die material and heat treatment in addition to reasonable structural design and processing accuracy.

Classification of mold steel

Mold steel can be roughly divided into three categories: cold-rolled mold steel, hot-rolled mold steel and plastic mold steel, which are used for forging, stamping, cutting, die-casting, etc.

Cold-rolled molds include cold punching dies, wire drawing dies, drawing dies, embossing dies, thread rolling dies, thread rolling plates, cold heading dies and cold extrusion dies, etc.

Hot-rolled molds are divided into several main types: hammer forging, die forging, extrusion and die-casting, including hot forging dies, press forging dies, stamping dies, hot extrusion dies and metal die-casting dies, etc.

Plastic molds include thermoplastic plastic molds and thermosetting plastic molds.
