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.


Loyal HMW partners know that we use the Christmas holidays every year to carry out maintenance and repair work.
We will therefore be closed again this year from 23.12.2023 to 01.01.2024.

Neither collections nor deliveries are possible during this period.
Last delivery: 22.12.2023

We will be back for you on 02.01.2024.
