Abstract
Method and apparatus for casting molten metal or alloy into a plurality of molds that are connected by mold ingate passages in melt flow communication to a melt supply passage which is configured in a manner to completely or partially fill the molds with the molten metal or alloy sequentially one after another. Filling of the molds in this manner provides uniform mold filling, reduces foreign matter in molds filled after the first-filled mold, and improves quality of the cast articles.
