Induction forming techniques –
Forging, pressing, bending

With forging, induction heating can save costs for many reasons. Inductive forge heaters can be easily automated and integrated into series production. They require little space compared to gas-fired furnaces and guarantee cost-effective energy consumption.

In addition, induction heating processes produce significantly less scale on the surface of the components (less than 0.5 %). On the one hand, this is an economic benefit, as less scale is introduced into the forming dies, giving them a longer service life. On the other hand, this creates a resource benefit, as no material is heated unnecessarily. Also due to the uniform ingot temperature and a uniform microstructure, there is better forming and less scrap.

Since induction systems can simply be switched off during phases of production interruptions, there is no unnecessary heating and thus no overheating. The inductive forging block heating systems do not require any warm-up times. And since there are no combustion residues, the environment is also polluted much less.

The specification-compliant temperature distribution through precisely fitting inductors is particularly important for the pressing of pipes and hollow profiles. This is because these enable balanced heating in the edge zones, so that no uneven edge thicknesses form. The bolt temperature, which drops towards the rear and compensates for the forming heat, can also only be achieved by inductive heating.
