Low temperature chemical heat treatment for CNC machining in Dongguan

According to Dongguan CNC processing manufacturers, ion nitriding can be used in order to improve the corrosion resistance, wear resistance, thermal fatigue resistance and anti-adhesion properties of the mold. The outstanding advantage of ion nitriding is that the nitriding time is significantly shortened, the structure of the nitriding layer can be controlled by adjusting different gas components, the surface brittleness of the nitriding layer is reduced, the deformation is small, the hardness distribution curve of the nitriding layer is relatively stable, and it is not easy to peel And heat exhaustion.

The permeable matrix material processed by Dongguan CNC is wider than gas nitriding, non-toxic, non-explosive, safe in production, but for molds with complex shapes, it is difficult to obtain uniform heating and uniform infiltration layer, and the infiltration layer is shallow, and the transition layer Steep, temperature measurement and temperature uniformity still need to be resolved.

The ion nitriding temperature should be 450~520℃. After 6~9 hours of treatment, the depth of the nitriding layer is about 0.2~0.3mm. If the temperature is too low, the seepage layer is too thin; if the temperature is too high, the surface layer is prone to loose layer, which reduces the ability to resist sticking.

According to the analysis of Dongguan CNC Machining Company, the thickness of ion nitriding layer should be 0.2~0.3mm. The worn ion nitriding mold can be put into use again after repairing and ion nitriding again, which can greatly improve the total service life of the mold.
