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.
