ABSTRACT:
A method and apparatus for casting parts comprising an open-faced mold which is displaced under a ladle. As the mold cavities, defined in the face of the mold, pass beneath the ladle, each is filled with molten material via a sprue in the bottom of the ladle. The ladle includes a venting conduit positioned within the sprue so that as the molten material empties into a mold cavity from the ladle, the air trapped within the mold cavity is vented through the sprue via the venting conduit.
