Patent ID: 7032640

Claim:
A method of molding a low melting point metal alloy comprising the steps of, while using a metallic raw material, which exhibits thixotropy properties in a solid-phase and liquid-phase coexisting temperature region, as a molding material, heating said molding material at a temperature in the solid-phase and liquid-phase coexisting temperature region to form a semisolid material, supplying a required amount of said semisolid material to a heating holding cylinder to be accumulated, and injecting said semisolid material into a mold by one shot from said heating holding cylinder, wherein a remaining semisolid material at an end of molding is heated at a liquidus temperature or higher to be melted, the material is injected in a wholly molten metal state and discharged from said heating holding cylinder, and heating is stopped so that the molding operation is finished.
