Induction Heating for Automotive Manufacturing

Within the automotive industry, induction heating has been used in the manufacture of large-scale parts for the main body, engine, electrical, steering, fuel and exhaust systems. With the broad operating frequency range of our automotive induction heating equipment, we're able to heat parts of virtually any size. Larger parts such as camshaft gears are heated at lower frequencies while smaller parts such as flexible electrical circuits are effectively heated at higher frequencies. Induction heating systems for automotive applications afford greater precision, quality, efficiency, and safety for your process heating needs.

Brazing steel flange and shaft assemblies (aerospace and automotive applications)

Induction brazing is a repeatable process that isn't as labor intensive as a flame often is. The process can heat the assembly rapidly and more energy-efficiently than a torch without the safety risks that come with an open flame

Brazing a steel tube and fitting to create an automotive valve

Customer's client was unhappy with the results from MIG welding, which drove them to look at induction as an alternative process. Induction heating proved to be a fast, repeatable heating method for the application...

Heat a compacted litz wire bundle for stripping

A three turn helical coil is used for the wire stripping process. The litz wire bundle is placed in the coil for 3 seconds to strip the lacquer 0.75 (19mm) from the end of the bundle. The wire bundle is then scraped with a metal brush to remove the burnt lacquer...

Heat aluminum for brazing an automotive assembly

A multi turn pancake coil is used to heat the joint between the aluminum tubing and boss. The joint heats to temperature in 1.5 minutes and the braze ring melts forming a clean brazed joint.

Brazing automotive tube assemblies

A four turn split helical coil is used to heat the steel assembly to 1400°F (760°C) for 85 seconds. The coil design allows for the steel fitting to expand away from the steel tube which allows braze to flow through the joint.

Preheating an automotive transaxle (welding)

The steel axle was painted with temperature indicating paint and a thermocouple was attached to the part.

Heating lead battery terminal for removal (recycling)

A single turn helical coil is used for this heating application. The lead terminal is placed inside the coil and is heated for 20 seconds.

Heating a motor prior to adding an injection molded part

Induction heating enables quicker process times with increased production rates versus a gas-fired oven. Ovens require long heat-up and cool-down times

Heating steel liners (engine head)

Precise direct heat to disengage the aluminium quickly and cleanly. The aluminium casing is recycled and reused thereby reducing scrap and cutting costs.

Heat automotive seat springs to powder coat

Even heating of the spring before dipping provides uniform flow and provides consistent thickness of the nylon coating

Heat the end of catalytic converter for weld testing

Heat the end of lorry catalytic converter exhaust system. The assembly must be held at target temperature for 200 hours, whilst the assembly is vibrated to test the weld strength

Heating Automotive Battery Cables for Adhesive Melting

Temperature indicating paint was applied to the parts, and it took 10 seconds to heat the various styles of the part to the targeted temperature. This testing achieved the client's time and quality objectives.

Bonding adhesive onto a steel washer for an automotive application

To heat a steel washer to the targeted temperature to enable adhesive curing; it will be part of an automated process for an automotive industry application

Bonding plastic with a steel gasket for an automotive application

Induction heating enables rapid bonding, can easily be integrated into the client's manufacturing process due to modest space requirements and delivers a highly repeatable process.

Sealing a Nylon Shell for a fuel vapor Assembly

Filter modules are assembled on the fixture with ring gasket. Pressure is applied to the modules, modules are rotated and induction heating is started. After 10-12 seconds, heating is halted and the modules are removed from the fixture.

Bonding Automotive Trim Vinyl Covering

Heating to 500°F is accomplished through the use of the unique coil; molding is continuously processed at a rate over 20 feet per minute.

Inserting a piston stop with o-ring into an oil pump assembly

Induction heating provides increased production speed, simpler tooling for customer, hands-free heating that involves no operator skill for manufacturing

Heating Four Inserts Simultaneously

The brass inserts are to be heated prior to insertion into a plastic automotive sub assembly

Brass Inserts

Heating is to be accomplished within 5 seconds, and can be done in a helical coil since pick and place manufacturing is employed.

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.

Bonding Rear View Mirror Brackets to Windshield Glass

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

Curing Alumium Car Molding

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

Soldering a Radio Antenna

To heat a coaxial antenna assembly to 600°F within 2 seconds for a soldering application. The goal to improve on an existing procedure with a soldering iron which required 10 to 15 seconds.

Soldering Solar Flex Circuits

Heat multiple joints on solar flex circuit strips to 500°F (260°C) within ten seconds for a soldering application.

Case Hardening of Armature Shaft

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.
