Abstract:
A system for pressure casting of a battery part to inhibit the formation of cracks and tears in the pressure casting of battery parts comprising:a mold member, said mold member carrying a portion of an internal mold cavity surface therein; a displaceable mold member, said displaceable mold member carrying a further portion of an internal mold cavity thereon with said displaceable mold member coacting with said mold member to form an internal battery part cavity of a first volume; and a power source for displacing said displaceable mold member into said mold member to form the battery part cavity of a first volume into a battery part cavity of a second volume, said second volume less than said first volume to thereby intensify the pressure of a battery part in the battery part cavity to thereby to thereby produce a pressure cast battery part substantially free of cracks and tears.
