Three Ways Of Heat Treatment Of Mold

- Jul 12, 2018-

The new process of die forging heat deformation heat treatment is gradually becoming familiar. Most of the die forging temperature is about 850 °C. After the last fire forging, it is not slow cooling, but cold quenching, and then high temperature tempering or spheroidizing annealing. Heat treatment can improve the life of the mold and better serve the public.


The heat treatment of the mold is divided into three parts: preliminary heat treatment, final heat treatment and surface strengthening.


The cold stamping die processed by vacuum heat treatment has less deformation and rarely causes cracking and cracking of wire cutting. The die-casting mold adopts an advanced process method to reduce the cracking of the mold and the phenomenon of sticking in use to a certain extent. At present, both domestic and foreign are trying to adopt more advanced vacuum heat treatment methods to improve the performance of the mold and prolong the service life of the mold. Vacuum heat treatment is one of the more advanced methods in mold heat treatment. Therefore, from the perspective of mold heat treatment, the state of the vacuum heat treatment processing equipment, the vacuum heat treatment process, and the control of the production process are particularly important. The advanced nature of the equipment is a prerequisite for ensuring the realization of advanced processes.


Vacuum heat treatment has the advantages of high quality, low energy consumption, no oxidation, no pollution, and the appropriate surface strengthening technology, which will give full play to the material potential.
