Vacuum heat treatment for plastic mold steel

Vacuum heat treatment combine vacuum technology and heat treatment technology, is the process of heat treatment in all and part of the vacuum state. Vacuum heat treatment can achieve almost all heat treatment process, it compared with the ordinary heat treatment has the following advantages.

• no oxidation , no decrease and no increase carbon, has a good protective effect on the workpiece surface and internal

• Improve the overall mechanical properties, degassing and promote the purification of the metal surface

• Workpiece deformation is small

• Able to reduce the workpiece metal element volatile
