Induction Hardening

The induction hardening is the technology of heating through the induced eddy current inside the workpiece. The heated workpiece, after fast cooling, will gain significantly improved hardness, wear resistance, and other mechanical properties.

Hardening is one of our main application areas. Our induction hardening machines are playing an important role in almost every industry, with the largest market to be automotive industry. The main advantage of induction hardening is the quick process time-it takes just a few seconds. In a furnace, however, the same process will take hours.

Comparing to ordinary quenching approach, the induction quenching has the following advantages:
1. with heat concentrated on workpiece surface, fast heating, high thermal efficiency;
2. selective heating, small deformation;
3. short workpiece heating time, slight surface oxidation and decarbonization;
4. small occupied area, easy to use, good working conditions;
5. facilitate mech-automation.
