Process performance in mold processing

Mold processing generally has to go through forging, cutting, heat treatment and other processes. In order to ensure the manufacturing quality of the mold and reduce the production cost, the material should have good forgeability, machinability, quenching, quenching and grinding, and should also have a small oxidation, decarbonization sensitivity and quenching deformation cracking tendency.
　　1. Mold processing forging
　　With low thermal forging deformation resistance, good plasticity, wide forging temperature range, forging cracking and the tendency to precipitate mesh carbide is low.
　　2. Mold processing annealing process
　　The temperature range of globulization annealing is wide, the annealing hardness is low and the fluctuating range is small, and the glorification rate is high.
　　3. Mold machining
　　The cutting amount is large, the tool loss is low, and the roughness of the machining surface is low.
　　4. Mold processing oxidation, decarbonization sensitivity
　　High temperature heating anti-oxidation bosom is good, the decarbonization speed is slow, the heating medium is not sensitive, the tendency to produce a little.
　　5. Mold processing hardening
　　After quenching, it has a uniform and high surface hardness.
　　6. Mold processing quenchability
　　After quenching, a deep hardening layer can be obtained, and the hardening media can be hardened with a gentle quenching medium.
　　7. Mold processing quenching deformation cracking tendency
　　The volume of conventional quenching is small, the shape warped, the distortion is slight, and the abnormal deformation tendency is low. Conventional quenching cracking sensitivity is low, and is not sensitive to quenching temperature and workpiece shape.
　　8. Mold processing can be grinding
　　The grinding wheel is relatively small in loss, the use of no burn limit grinding is large, is not sensitive to the quality of the grinding wheel and cooling conditions, and is not easy to break and crack.
