Induction Heating Steel Mold For Rubber Seal With High Frequency Heating System
Objective To heat a steel mold evenly to 392ĀŗF (200ĀŗC) to be used on aĀ press for rubber seal vulcanization
Material Steel mold 13.4ā (340mm) diameter, 2.16ā (55mm) width,
approximately 77.2 lbs (35kg)
Temperature 392ĀŗF (200ĀŗC)
Frequency 20kHz
Equipment ā¢ DW-MF-70kW induction heating system, equipped with aĀ remote workhead containing eight 0.3Ī¼F capacitors for aĀ total of 0.6Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process Two thirteen turn pancake coils are used to heat both sides ofĀ the mold simultaneously for 170 seconds to reach an externalĀ temperature of 392ĀŗF (200ĀŗC). The power is continuallyĀ decreased over the next 390 seconds to reach a uniformĀ temperature of 392ĀŗF (200ĀŗC) Ā± 41ĀŗF (5ĀŗC) throughout the
mold.
Results/Benefits Induction heating provides:
ā¢ Repeatable and consistent heat
ā¢ Quicker process time, increased production
ā¢ Even distribution of heating
