The heat treatment mode of mould (Die casting companies) steel is closely related to the processing schedule. In the mold manufacturing, should be based on materials and processing routes to choose heat treatment methods, formulate corresponding heat treatment process. 

(1) the heat treatment procedure of the cold work die steel work parts: make - annealing - mechanical forming - quenching and tempering - finishing. 

(2) cold working die steel is formed by shape grinding and electro processing: forging - annealing - Mechanical roughing - quenching or tempering - finishing (grinding, machining). 

(3) cold die steel processing of complex die: forging - annealing - Mechanical roughing - high temperature tempering or conditioning - mechanical processing - quenching and tempering - grinding and electrical processing molding. 

Most of the cold die steel used for quenching and tempering condition, die hardness is usually 60HRC, in order to further improve the mould surface hardness, wear resistance and service life, often surface strengthening treatment, such as carburizing, nitriding and boronizing nitrocarburizing, TD method, chemical vapor infiltration of vanadium niobium (CVD) as the product of the village the final heat treatment.
