Steel Die Induction Heating


Steel die induction heating in a thermal process of an enclosed powder

Objective : A steel die is heated with induction in a thermal process of an enclosed powder

Material: Steel die with a compressed powder solid inside

Temperature: 400 ºC (750 ºF)

Frequency: 22 kHz

Induction Heating Equipment: DW-MF-70kW/30kHz induction heating system, equipped with a remote workhead containing one 53μF capacitor
– An induction heating coil designed and developed specifically for this application.

Process Induction Heating is evaluated to replace an oven/batch process.
Advantages include reduced heating/cooling ramp times and floor space requirements.
A nine-turn helical induction heating coil is used to heat the steel die while temperature of the die is monitored with a thermocouple. Die heating soak time is one hour.
