Abstract
An assembly disposed within a mold for forming openings in a plastic part includes a punch pin and a backing pin having faces disposed flush with a surface of a mold cavity. The backing pin is disposed opposite the punch pin. The punch pin is driven into the completed plastic part removing material to form an opening. The waste material is driven into a bore housing the backing pin. The backing pin recedes into the bore to accept the waste material. Upon ejection of the plastic part the waste material ejects from the mold cavity as the backing pin moves back to a position flush with the surface of the mold cavity.
