How much do you know about the manufacturing process performance of the mold?
The manufacture of molds generally has to go through several processes such as forging, cutting, and heat treatment. In order to ensure the manufacturing quality of the mold and reduce the production cost, the material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity and quenching. Deformation and cracking tendency.
1. Forgeability
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency for forging cracking and cold cracking and precipitation of network carbides.
2. Annealing manufacturability
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
3. Machinability
The cutting amount is large, the tool loss is low, and the machined surface roughness is low.
4. Oxidation, decarburization sensitivity
When heated at high temperature, it has good anti-oxidation energy, slow decarburization Auto parts Mould speed, insensitivity to heating medium, and small tendency to produce pitting.
5. Hardenability
It has a uniform and high surface hardness after quenching.
6. Hardenability
After quenching, a deep hardened layer can be obtained, which can be hardened by using a mild quenching medium.
7. Quenching deformation cracking tendency
The volume change of conventional quenching is small, the shape is warped, the distortion is slight, and the abnormal deformation tendency is low. Conventional quenching has low cracking sensitivity and is not sensitive to quenching temperature and workpiece shape.
8. Grindability
The relative loss of  Household appliances Mould the grinding wheel is small, the limit grinding amount without burns is large, it is not sensitive to the quality of the grinding wheel and the cooling conditions, and it is not easy to cause abrasion and grinding cracks.
