The Question

Why inductive annealing?

  • Less distortion

    Heat is introduced in a targeted manner, limiting unnecessary heat load on the entire product.

  • Highly reproducible

    Power, time, position, and temperature can be accurately recorded and repeated.

  • Energy-efficient process

    Only the desired area is heated. This makes the process fast, efficient, and clean. Ask your question.

Applications

Applications of induction annealing

For steel, stainless steel, and other metals

Suitable for a wide range of geometries, from tubes and rings to local zones on larger parts.

From single pieces to series production

The process can be performed manually, semi-automatically, or fully automatically.

Optional with temperature control

With a pyrometer and closed-loop control, the annealing temperature remains stable and reproducible.

Key benefits

  • Specialist in induction heating since 2006
  • In-house laboratory for process testing
