  • Patent number: 5048590
    Abstract: A method and an apparatus for forming a battery terminal bushing from a molten lead alloy in order to substantially eliminate the porosity in the material of the finished bushing. This method and apparatus includes the heating of the lead alloy until molten, pouring the molten alloy into a mold cavity, forcing a punch centrally and longitudinally through the center of the mold cavity not only to remove the core from the center of the material which will form the bushing, but also to simultaneously force the remaining alloy within the mold cavity campactly against the inner surface of the mold cavity, withdrawing the punch and ejecting the finished bushing of high density and a polished exterior surface, substantially free of air pores within the bushing material.
