Production Automobile

Dans l’industrie automobile, le chauffage par induction a été utilisé à des fins de production des pièces de grande taille pour la carrosserie, moteur, système électrique, système de direction, système de carburant et système d’échappement. Avec des systèmes de chauffage par induction qui couvrent une très vaste plage de fréquences, nous sommes capables de chauffer des pièces de toutes dimensions. Les pièces de plus grande taille, telles que, des engrenages d’arbres à cames sont chauffées à des fréquences inférieures alors que des pièces plus petites comme, par exemple, des circuits électriques flexibles sont chauffe à des fréquences supérieures.

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

A five turn helical coil is used to heat the gear end of the shaft to 1700°F

Aluminum motor housing; automotive

Induction heating is fast, presents significant energy savings over an electric oven, requires a more modest footprint than an oven and can be easily integrated into an automated process

Shrink-fitting a gear securely on a shaft (automotive)

The customer was using a torch, which can lead to inconsistent part quality. Induction's precise heating means the client can count on consistent results in their process

shrink-fitting aluminum pulley to insert inner bearing

A three turn helical coil is used to heat the aluminum pulley. The pulley is heated to 464 °F (240 °C) in 20 seconds to expand the inner diameter and then the inner bearing is inserted to form the completed part.

shrink-fitting an assembled wrist pin into a connecting rod

Induction heating provides more accurate control of heat vs a flame burner, it heats only the knuckle, not the whole part, it prevents discoloring due to lower temperature used and increases productivity due to repeatability & ease of operation. A foot pedal & timer is used.

Shrink Fitting Cam Shaft Gears

The power was turned on for five seconds and the part was monitored during heating and for 15 seconds after.

Preheating Rod Assemblies for Welding

The client had been using torches for preheating. However, due to process improvements thanks to new automation in their facility, torch heating became too slow. This resulted in a backlog that kept them from maximizing their throughput.

Curing coating on a steel brake rotor

This treatment improves the appearance of today’s more exposed wheel internals and eliminates certain masking parts.

À propos du chauffage par induction

Chauffage par induction

Il est une méthode rapide, efficace, précise et répétable, sans contact permettant de chauffer les métaux ou les autres matériaux conducteurs d'électricité. Le matériau peut être un métal comme de l'acier, du cuivre, de l'aluminium, du laiton ou cela peut être un semi-conducteur comme du carbone, du graphite ou du carbure de silicium. Pour chauffer les matériaux non conducteurs comme le plastique ou le verre, l'induction est utilisée pour chauffer un suscepteur conducteur d'électricité, habituellement le graphite, qui transfère ensuite la chaleur du matériau non conducteur.

Bobines d'Induction

Bobines d'Induction

La bobine d’induction, ou inducteur, est le composant du système de chauffage par induction qui détermine l’efficacité et le rendement du chauffage de la pièce.

La bobine sert à transférer l’énergie de l’alimentation en puissance et de la tête d’induction à la pièce, en créant un champ électromagnétique alternatif.
