The manufacturing of a mold maker generally requires several processes such as forging, cutting, and heat treatment. In order to ensure the manufacturing quality of the mold maker and reduce the production cost, its material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity and Tendency of quenching deformation and cracking. Let’s follow the Aluminum Extrusion cnc from China manufacturer editor to have a brief look at it!


1. Malleability
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency of forging cracking and cold cracking and precipitation of networked carbides.
2. Annealing processability
The spheroidizing annealing temperature range is wide, the annealing hardness is low, 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. Sensitivity to oxidation and decarburization
When heated at high temperature, the oxidation resistance is good, the decarburization speed is slow, the heating medium is not sensitive, and the tendency of pitting is small.
5. Hardenability
After quenching, it has uniform and high surface hardness.
6. Hardenability
After quenching, a deeper hardened layer can be obtained, and it can be hardened by using a mild quenching medium.
7. Tendency of quenching deformation and cracking
Conventional quenching has small volume changes, shape warping, slight distortion, and low tendency of abnormal deformation. Conventional quenching has low sensitivity to cracking, and is insensitive to quenching temperature and workpiece shape.
8. Grindability
The relative wear of the grinding wheel is small, and the limit of grinding without burn is large. It is not sensitive to the quality of the grinding wheel and cooling conditions, and it is not easy to cause abrasion and grinding cracks.
The above is the editor of Aluminum Extrusion cnc from China manufacturer: I hope you can learn more about the relevant knowledge of mold maker process performance.
