<p>A die casting process, and a die casting apparatus make it possible to produce high-quality cast products, which little involve gas defects, with simplified constructions, such as an electromagnetic induction coil disposed around a plunger sleeve, and a contractible container disposed movably in a plunger sleeve. With these simplified constructions, a molten metal is localized on a side of a retracted plunger chip disposed in the plunger sleeve. Accordingly, when the retracted plunger chip is advanced, only gases, contained in the plunger sleeve, can be transferred to a cavity of a mold at first, and thereafter the localized molten metal can be injected into the cavity. Thus, it is possible to effectively inhibit the molten metal from involving the gases. <IMAGE></p> |
