Induction Susceptor Heating

What is Susceptor Heating?

A susceptor is induction heated, conducting energy to the work material. Susceptors are made from silicon carbide, molybdenum, graphite, stainless steels and other conductive materials.

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 susceptor.

Induction susceptor heating Benefits

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
