Induction Hardening

We have been using the induction hardening process in our company since 1964.

For this we are using both high-frequency and medium-frequency machinery. Since quality is the highest of all goods we can carry out our own hardness tests.

Hard and Stable - Hardening by Induction Heating

Inductive surface hardening is a process for the quality refinement of workpieces made of steel, cast iron and cast steel.
The material is hardened by heating a certain area of the workpiece, so-called partial heating. This hardening takes place mainly in zones subject to particular stress. The zone is heated to an austenitizing temperature of approx. 900° C within a few seconds and is directly quenched by air, water, oil or emulsion.

The advantages of induction heating include

• Partial Hardening
• Quick Warming
• High Throughput
• Reproducible Control of the Hardening Process
• Low Scaling
• Minimum Warpage
• No Coarse Grain Formation

As a specialist in induction hardening, we also have our own inductor production.

In our shuttle kiln plant we have a capacity of 26t.
The gas-powered furnace can be heated up to 600° C.

In order to guarantee a permanently perfect quality, we have our own magnetic particle crack testing.
This allows us to detect possible crack formations at an early stage and adjust the hardness parameters accordingly.

With our vertical high-frequency hardening machines

• in the power range 40 to 180 kW
  and 
• hardening length of up to 1600 mm

we are able to achieve an edge hardening depths of up to 5 mm.

In our company there are both

• Horizontal hardening machines from 70 to 150 KW
  as well as
• Vertical hardening machines from 120 to 600 KW in the 10 and 2.5 KHz range.

With our machines we able to manufacture a hardening length of up to 3800 mm.
The medium frequency hardening machines allow edge hardening depths of 3 mm to 35 mm.
