Abstract
The casting apparatus and method include a magnetically responsive valve disposed in the molten metal inlet passage of the mold for movement between an open position during mold filling and a closed position after mold filling and during removal of the mold from the underlying molten metal pool to prevent run-out of molten metal from the metal-filled mold cavity. The valve is moved to the closed position by a magnetic force exerted thereon by permanent magnets or an electromagnet disposed around the inlet passage below the valve.
