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.

Abstract:
Method and apparatus for forming a wheel hub by means of a casting process which involves providing additional material during the casting process at the perimeter of the hub in quantity sufficient to form a rim; spin-forming a rim about the hub using the additional material provided during the casting process; machining mounting features in the hub; and machining finish features into the rim.
