Abstract

Method and apparatus for flowing molten metal substantially vertically into a mold by means of a feeder tube while concurrently impeding the flow of oxides that collect at the perimeter of the head of the feeder tube. This reduces inclusions in the molten metal and improves the quality of a molded component as the molten metal solidifies.
