ABSTRACT:
In a casting apparatus, an electromagnetic pump is installed above a mold cavity. A molten metal contained in a crucible is forced into the mold cavity. The electromagnetic pump acts not only to exhaust gas or air in the mold cavity but also applies a downward force to the molten metal rising above the upper surface of the mold cavity.
