ABSTRACT:
One or more holes that extend through a wall of a powder metal component are formed by creating an absence of powder metal in a die set during compaction at an interface between a side surface of a punch and another side surface of the die set that faces the side surface of the punch in substantially close proximity to create the absence of powder metal at the interface.
