Advanced vacuum heat treatment can extend the life of the mold

As an indispensable and important equipment in the manufacture of machinery industry, molds are more convenient for the manufacture of similar products, and at the same time bring a certain downward adjustment to the production cost, but the heat treatment is an important processing step, the following main expand around this.

Usually, the final forging temperature of most molds is about 850 °C. After the last fire forging, it is not slow cooling, but fast cold quenching, and then high temperature tempering or spheroidizing annealing. Heat treatment can improve the life of the mold, and 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.

Air cooling Vacuum Gas Quenching Furnace is applied for quenching high-speed tool steel, measuring vacuum hardening and cutting steel, tool steel and other alloy steel, with convection heating function, which can achieve the process of step hardening, isothermal quenching, but also tempering, annealing, carburizing, nitriding and other heat treatment process. Ultimate pressure :cooling gas ,6Bar or 10Bar.

The control system was controlled by PLC, temperature was controlled by intelligent temp controller, accurate control,high automation. User can choose auto or manual undisturbed switching tooperate it, this furnace has abnormal condition alarming function, easy to operate.

Environmental protection performance of vacuum furnace has been improved, maintenance cost saving, energy cost saving.
