Process Performance Of The Mold

The manufacturing of molds generally involves several processes such as forging, cutting, and heat treatment. To ensure the manufacturing quality of the mold and reduce production costs, the material should have good malleability, machinability, hardenability, hardenability, and grindability; It should also have a small sensitivity to oxidation, decarburization, and a tendency towards quenching deformation and cracking.
1. Forgeability
It has low resistance to hot forging deformation, good plasticity, wide forging temperature range, low tendency for cold cracking and precipitation of network carbides during forging.
2. Annealing process
Spheroidization annealing has a wide temperature range, low annealing hardness and small fluctuation range, and high spheroidization rate.
3. Machinability
The cutting amount is large, the tool loss is low, and the machined surface roughness is low.
4. Sensitivity to oxidation and decarbonization
When heated at high temperatures, it has good antioxidant capacity, slow decarbonization speed, is not sensitive to the heating medium, and has a small tendency to produce pitting.
5. Hardenability
After quenching, it has a uniform and high surface hardness.
6. Hardenability
After quenching, a deeper hardening layer can be obtained, and quenching can be achieved using a mild quenching medium.
7. Quenching deformation and cracking tendency
Conventional quenching has small volume changes, slight shape warping and distortion, and low tendency for abnormal deformation. Conventional quenching has low sensitivity to cracking and is not sensitive to quenching temperature and workpiece shape.
8. Grindability
The grinding wheel has relatively low wear and tear, and the maximum grinding amount without burns is large. It is not sensitive to the quality and cooling conditions of the grinding wheel, and is less prone to grinding injuries and cracks.
