Abstract
A method of removing voids from a casting is disclosed including the steps of introducing molten metal into a die, providing an impact surface and dropping the die containing the molten metal at least once from a predetermined height to strike the impact surface. A device for removing voids from a casting includes a base, a drive means operably coupled to at least one cam, and a guide configured to receive a die, wherein the at least one cam is positioned on the base to contact a die placed on the guide, and wherein rotation of the at least one cam is operable to raise and subsequently release the die to strike a surface of the base, and wherein the guide maintains the die in a stable orientation relative to a horizontal axis of the base.
