Abstract

A system for manufacturing a cast alloy wheel includes a mold defining a die cavity being configured to form the alloy wheel that includes a face portion and a. rim portion. A furnace heats the alloy to maintain the alloy in a molten state. A feeder box interconnects the furnace to the mold providing molten alloy to the die cavity. The feeder box defines a gate system with a central axial runner for providing molten alloy to the face portion of the die cavity. A plurality of rim runners provides the molten alloy to the rim portion of the die cavity.
