ABSTRACT:
A billet (10) is pressed with a first blocking punch (36, 38). Thereafter, the billet is rotated approximately 90.degree.. A second punch (50) is pressed against the billet while a split ring die assembly (58) substantially surrounds the billet and constrains outward flow of the steel. The split ring die assembly includes projecting regions (64, 66) matingly received in recesses (14, 16) created by the first blocking punch. A finishing punch (90, 92) is pressed through the billet to complete formation of openings (94, 96). Preferably, a trimmer (100) removes any flashing from the finished billet.
