Induction Heating Automotive Motor

Induction Heating Automotive Motor With High Frequency Induction Heating Machine

Objective Heat steel to help bond an injection molded piece and help the reflow.
Material Steel motor body, 60 x 60 x 27 (2.4 x 2.4 x 1.1) mm(in)
Temperature 260ºC (500ºF)
Frequency 237 kHz
Equipment •DW-UHF-10kW induction heating system, equipped with a remote workhead containing a total 1.5 μF.
• An induction heating coil designed and developed specifically for this application.
Process/Narrative A two-turn binocular coil is used to simultaneously heat two steel motors prior to the injection molding process. This helps increase the bond strength between and reflow the plastic.
Results/Benefits Induction heating provides:
• Quicker process times with increased production rates versus a gas-fired oven. Ovens require long heat-up and cool-down times.
• Significantly reduced footprint
• Reduced handling due to location of the induction coil in proximity to the injection molding machine.

Brazing Automotive Parts With Induction

Brazing Automotive Parts With Induction

Objective: To braze a automotive steel tube to a steel “T” fitting
Material 1” (25.4mm) diameter steel tubing, steel fitting, braze slug and black flux
Temperature 1400ºF (760ºC)
Frequency 200 kHz
Equipment • DW-UHF-10 kW induction heating system, equipped with a remote workhead containing two 1.0μF capacitors for a total of 0.5 μF
• An induction heating coil designed and developed specifically for this application.
Process A four turn split helical coil is used to heat the steel assembly to 1400ºF (760ºC) 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. The amount of braze alloy is controlled by the braze slug allowing for an aesthetically pleasing joint.
Results/Benefits Induction heating provides:
• Hands-free heating that involves no operator skill for manufacturing
• Precise and uniform distribution of heating
• The collection of flux on the coil is reduced due to efficient coil design.
