Zusammenfassung:	A metal casting apparatus (20) includes a feeder (22) for providing a molten metallic material. A mold (26) includes a sprue (28) and a component cavity (30). The sprue (28) is arranged to receive the molten metallic material from the feeder (22) and the component cavity (30) is arranged to receive the molten metallic material from the sprue (28). A starter (32) is arranged adjacent the component cavity (30) and is operable to induce a first grain orientation upon solidification of the molten metallic material. The sprue (28) includes an aborter (34) that is arranged to induce a second grain orientation upon solidification of the molten metallic material.
