Abstract
The present application discloses an injection molding apparatus including a heating injector which heats and melts a conductive material to a molten temperature. The heating injector injects the conductive material into a mold with a cavity formation surface which forms a cavity. The injection molding apparatus includes an electrifying portion configured to apply a voltage; and a controller including an electrification controller configured to control the voltage which is applied by the electrifying portion. The mold includes conductive portions at least on a part of the cavity formation surface. The conductive portions are insulated from each other. The electrifying portion applies the voltage between the conductive portions. The conductive material injected from the heating injector is electrically heated by the voltage, which is applied from the electrifying portion under control of the electrification controller, when the conductive material comes in contact with the conductive portions.
