Abstract
A metal object forming method includes a preliminary step and a metal-injecting step. At the preliminary step, flowability-improving material is put in a molding die. Then, at the metal-injecting step, molten metal is poured into the die for producing a casting. Due to the high temperature of the molten metal, the flowability-improving material melts into the molten metal, to cause the freezing point depression of the molten metal.
