Note: Heating a motor prior to adding an injection molded part
Objective:
Heat steel to help bond an injection molded piece and help the reflow.
End Product:
Steel motor body
Equipment:
Ambrell 6 kW 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
Materials:
Steel motor body 2.4 x 2.4 x 1.1 in (60 x 60 x 27 mm)
Temperature:
500 °F (260 °C )
Frequency:
237 kHz
Testing:
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
Benefits:
-
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.
