Why use induction for fastener heating?

To improve production rates and fastener quality, fastener manufacturers use heat in their heading, threading and patching production processes. With induction heating, fasteners are heated quickly, efficiently, and with maximum repeatability.

Is induction appropriate for hot heading?

Induction heating is commonly used for preheating bolt and screw heads prior to forging, offering many benefits for the warm or hot heading processes.

Can it be used to cure paint or powder?

Induction heating is ideal for curing the paint or powder material used in thread patching. It can greatly improve thread patching productivity by rapidly heating fasteners up to 300° C for flowing the paint or powder coating.

Induction in Fastener Manufacturing

Improve production rates and fastener quality; consider induction heating for your heading, threading and patching processes. Fasteners are heated quickly, efficiently, and with maximum repeatability.

Induction fastener 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
