Inductive hardening

Induction hardening

Hardening of complicated shaped workpieces

Induction hardening quite clearly differs from other hardening processes, as the heat is generated directly in the workpiece and thus a very gentle way of heating takes place. This heating takes place primarily partial, so it does not affect the entire workpiece.

There are clear advantages such as the low distortion. The method of operation is very clean, and the rapid rate of heating requires only minimal post-processing; At the same time a very uniform hardening depth is achieved. The oxidation and the distortion are negligible.

Induction hardening is particularly well suited to workpieces that are subjected to exceptionally high levels of load, such as specific gears. Also crankshafts, rollers and valve tappets are good examples of the ideal application of induction hardening, as well as workpieces that are exposed to a high alternating and / or shock load.
