Induction heating device is used to heat die ring to a reasonable temperature, which make the inner hole of die a little larger and easy assemble with die shaft. In traditional, the die is heated by putting it into hot oil. Compare with oil hot, use induction heating device is cleaner, and the heating temperature is controllable, visible, and more stable.
