induction heating machine for hardening and tempering


1, High conversion efficient more than 97.5%

2, IGBT inversion technology

3, Proper coil design

4, Localized heating, less hardening distortion

5, Heat depth can be limited to just the surface or can include the entire cross section

6, Reduced heat and quench times

7, Uniform heating temperature

8, Surface hardening retains original ductility of core

9, improved part quality

10, Hardening depth from 0.8mm to 10mm



1, It treats a specific part of the piece (hardening profile)

2, Frequency Control and heating times

3, Cooling control

4, Energy saving

5, No physical contact

6, Control and located heat

7, Can be integrated in production lines

8, Increase performance and saves space

9, Induction hardening is faster than other forms of hardening.
