In simple terms, heat treatment refers to a treatment that hardens or softens a metal, thereby changing its mechanical properties. For example, the axles, engines and transmissions of automobiles, hinge parts of notebook computers, parts of printer printing units, drive motors of automatic ticket gate gates in stations, and contacts of mobile phones are numerous. Although there are many heat-treated items around you, because the heat treatment itself is not visible, it is not easy to be noticed by people. In fact, heat treatment is helping everyone behind the scenes.

Nowadays, the electronicization of heat treatment equipment continues to develop, and the number of operations that are purely intuitive as before has decreased, but the process of heat treatment processing is still invisible, so management is very difficult. When it is mainly used for heat treatment of auto parts, a very high level of quality control is required.
