Mold Meets Process Performance Requirements
- Sep 14, 2017 -

Mold manufacturing generally have to undergo forging, cutting processing, heat treatment and other processes. In order to ensure the manufacturing quality and reduce the production cost, the materials should have good forging, machinability, hardening, hardenability and grinding, and also have small oxidation, decarbonization sensitivity and quenching deformation tendency.

1, malleable
It has lower thermal forging resistance, good plasticity, wide forging temperature range, low forging crack and precipitated net carbide tendency.

2. annealing process
The annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, the ball rate is high.

3, cutting processing
Large cutting amount, low tool loss and low roughness of machined surface.

4, oxidation, decarbonization sensitivity
High temperature resistance to oxidation can be good, decarbonization speed is slow, the heating medium is not sensitive, resulting in a small tendency of pitting.

5, quenching and hard
After quenching, it has uniform and high surface hardness.

6. hardenability
After quenching, the hardened layer can be obtained, and the quenching medium can harden.

7, quenching deformation cracking tendency
The conventional quenching volume changes small, the shape warping, the distortion is slight, the abnormal deformation tendency is low. The conventional quenching cracking sensitivity is low, which is insensitive to quenching temperature and workpiece shape.

8, can be grinding
The relative loss of the grinding wheel is small, and the maximum grinding amount of no burn is not sensitive to the quality and cooling conditions of the grinding wheel.
