<p>An apparatus performs induction heating or dielectric heating of a mold for an injection molding system up to a desired temperature within a short time by using high frequencies or microwaves. The electric current of high frequency generated from a high frequency generator (140) flows through a coil (150) embedded in the mold (160) to induction-heat the mold by an induction phenomenon with the mold, and microwaves from a microwave generator heats the dielectric material within the mold, thereby preventing cooling of the mold when a resin fluid is injected into a cavity.</p> |
