Induction Curing

Curing involves any process where heat is used to catalyze or initiate chemical and molecular level structural changes in a polymeric materials such as epoxies, phenolics, polyesters and silicones. These materials are applied in many ways to various products for bonding, protective coating, sealing, insulation and other uses.

Air curing and hot fan curing are often used for curing small production runs, despite inconsistent results. Large production runs often are cured in batches in large ovens which must be run continuously. Induction heating provides a much better solution for adhesive curing.

Curing a coating by heating a steel tube and an aluminum block

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.

Curing plastisol adhesive on both ends of a filter assembly

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

Curing a coating on both sides of an aluminum piston

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.

Curing epoxy on aluminum copier roller assembly

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.

Curing plastisol adhesive on an aluminum filter assembly

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.

Curing ink on aluminum bottle caps

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.

Curing Alumium Car Molding

Automotive manufacturers are constantly searching for cost-effective production technologies.

Curing Ceramic Fiber

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

Curing Speaker Cone Epoxy

Induction heating provides minimized coating defects, repeatable results and faster production times

Curing the Inside Liner of Baby Food Bottle Tops

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.

Bonding Rear View Mirror Brackets to Windshield Glass

A unique four-over-four double wound pancake coil is used for the bonding application.

Curing Adhesive on Steel Motor Shaft for Bonding

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.

Curing Measuring Tape Paint

The Ambrell 20kW output solid state induction power supply along with a unique 30" long multi turn helical coil was found to produce the following results.

Curing Epoxy On A Laser A Laser Diode Assembly

To heat epoxy on a laser diode assembly to 250°F within 5 seconds for a curing application

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
