How Induction Curing Works
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 curing 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
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.

Induction heating provides improved distribution of heat, much faster cure time than heat plates previously used, much faster production rate and hands-free heating that involves no operator skill for manufacturing
A three turn channel coil 19 (48.26cm) long is used to anneal 4 pistons running though the coil with a distance of 6 (15.24cm) between centers.
A four turn helical pancake coil is used to heat the end of the copier roller assembly. The assembly is heated 90 seconds to cure the adhesive.
A four turn helical coil is used to cure the plastisol adhesive. One filter end cap is filled with adhesive, attached to the filter and heated 90 seconds to cure the adhesive.
A double channel coil is used for the ink drying application. Fifteen bottle caps are placed inside the coil and power is applied for 3 seconds to dry the ink.
Automotive manufacturers are constantly searching for cost-effective production technologies.
A special steel tube and coil combination is used to build an induction heating oven to cure the fiber on a continuous basis. The ceramic fiber travels in an alumina tube inside a hot steel tube
Induction heating provides minimized coating defects, repeatable results and faster production times
A three turn oval pancake coil is used to cure the inside liner of a baby food bottle cap. The bottle cap travels through the coil at 25 per second to cure 500 caps per minute.
A unique four-over-four double wound pancake coil is used for the bonding application.
A complex two coil system, shield and stud systems used to provide proper axial alignments of the shaft & coil while allowing the fixture to be open for removal of the shaft.
The Ambrell 20kW output solid state induction power supply along with a unique 30 inch long multi turn helical coil was found to produce the following results.
