  • Die casting apparatus and process comprising in-die plunger densification to form a bore through a product casting
    Patent number: 4779665
    Abstract: A die casting process and apparatus is described for forming a metal casting having a bore therethrough surrounded by dense, nonporous metal. During solidification, a plunger core is driven through the metal to substantially form the bore. The plunger core comprises a metal-penetrating conical tip that laterally displaces metal in response to plunger core advance to densify the metal about the bore. The plunger core tip is received into a correspondingly shaped recess so that only a thin metal flash is formed therebetween, which flash is readily removed by punching to complete the bore.
