The shaped work piece in the die cavity can be released when the solidified alloy is heated to melt, and an inner die for a different die cavity can be substituted for the old one, and {HEAD ~ an effect} of {TAIL ~ recovery} for reusing the filler can be achieved, and cost of forming can be reduced
