5. Under the condition of ensuring the hardness of the mold, try to use pre-cooling, staged cooling quenching or warm quenching process.
6. For precision and complex molds, vacuum hardening and quenching after cryogenic treatment should be used as far as possible.
7. For some sophisticated molds, pre-heat treatment, aging heat treatment, quenching and nitriding heat treatment can be used to control the precision of the mold.
8. When repairing defects such as sand holes, pores, and abrasion of the mold, use a cold-welding machine and other small heat-affecting repair equipment to avoid deformation during the repair process.
There are many methods for heat treatment process, including, for example, plugging, tying holes, mechanical fixing, proper heating method, accurate selection of the cooling direction of the mold, and the direction of movement in the cooling medium. The fair tempering heat treatment process is also reduced in complexity. Effective measures for mold deformation.
