Induction Bonding Plastic with a Steel Gasket (Automotive)
Induction bonding enables rapid heating, 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
Bonding of electric motor shaft to nylon face fan
Induction heating provides hands-free heating that involves no operator skill for manufacturing, only the metal shaft is heated so the motor is not affected, increased production due to rapid heating, decreased failure rate, originally used glue which ran into motor and caused failure and stronger bond
Heating Four Inserts Simultaneously
The brass inserts are to be heated prior to insertion into a plastic automotive sub assembly
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.
Automotive manufacturers are constantly searching for cost-effective production technologies.
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.
