Induction Curing

How Does Induction Curing Work?

Induction heating provides a better solution for adhesive curing than air curing, hot fan curing or curing in large ovens which must be run continuously. Induction is used to heat the metallic material on which the curing adhesive has been applied

Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpieces to be heated.

Benefits of induction curing

Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
Increases production rates with faster heating cycles
Reduces defect rates with repeatable, reliable heat
Eliminates variability from operator-to-operator, shift-to-shift
Maintains metallurgical characteristics of the individual metals

The client's oven had a heating time of 20 minutes, so the time savings from a 90-second cycle are considerable. Additionally, induction is a repeatable process, unlike an oven and the induction system takes up less floor space than an oven.
