Low frequency induction hardening

Biagini Industries srl (in wich it evolved Biagini Tempra Metalli srl) has always invested in the latest technologies and systems to better meet the demands of customers who wish to harden their products through the method of induction hardening.

In fact we were among the first to invest in variable frequency systems, an important factor considering that in this way you can increase the types of details handled on the same system.

We have 10 IGBT generators with medium-LOW variable frequency.

Current machinery includes 17 systems for induction hardening with high, medium and low frequency and power ranging from 100 kW to 1000 kW. The frequency range allows us to achieve a hardening depth from 0.5 mm to 30 mm. Power on the other hand gives us the possibility to range from small to large size details.

How does low frequency induction hardening differ from high and medium frequency?

Low-frequency induction hardening is a type of heating employed to harden to considerable depths up to and exceeding 30mm. High frequency induction hardening is used for hardening depths from 0.6 to 2 mm; medium frequency induction hardening, lastly, is used for heating to depths 2 to 6 mm.

The working frequency, and the power of a system for induction hardening must be selected according to the requirement for the hardening depth to be obtained, and the size of the component to be hardened.

To evaluate which solution best suits your production needs, please contact us; we are convinced that the keys to success are research, innovation and experience. Our highly qualified personnel, through the use of the very latest quality machinery, will be able to satisfy your every need.

Power is in our hands.
