Abstract
In a molding machine, an electrical current is caused to flow to a coil by a high-frequency power supply, and a magnetic field is generated, whereupon lines of magnetic force are generated so as to substantially conform to cavity faces of the stationary mold and the moveable mold. The magnetic field strength is constant with respect to position in the lengthwise direction of the coil, and eddy currents are generated uniformly with respect to the cavity faces. Because the molds have electrical resistance, Joule heat is generated by the eddy currents and electrical resistance, and the cavity faces are heated. When a material in a molten state is injected into the cavities of the heated molds, flowability of the material is promoted, and therefore the quality of the molded article is improved.
