What is induction post-heating?

Induction post-heating refers to any process where induction is used to heat workpieces or materials that have already undergone significant processing. Metal components and welds, for example, must often be post-heated to relieve internal stresses caused by a previous process. Induction post-heating is also used to heat cable cores following extrusion.

 

What are the benefits?

The speed, versatility, precision and controllability of induction make it ideal for numerous post-heating tasks. Our cable and wire post-heating systems, for instance, induce localized heat directly in the cable core. This results in extremely fast cross-linking of the insulation’s polymers. At the same time, induction minimizes the risk of cable deformation. Our mobile Minac systems bring the benefits of induction to flame-free sites such as offshore oil and gas platforms.

 

Where is it used?

Our post-heating solutions are mainly used in the cable and wire, tube and pipe, electrotechnical and aviation industries. In the automotive industry, rings, shafts, joints and gears as well as cure corrosion-resistant brake disc covers are post-heated. Induction is also used for tin re-flow applications.
