PROBLEM TO BE SOLVED: To provide a slush casting method which enables the mass production of the mixed-flow production using resin materials having different melting temperatures. SOLUTION: The slush casting method comprises: a heating process of heating a mold with a heating furnace; a forming process of filling up the heated mold with a powder-like resin material and making the resin material adhere to the inside of the mold in a required thickness to obtain a melting resin molding; a cooling process of cooling the mold having obtained the melting resin molding by cooling water and hardening the melting resin molding; and a mold removal process of taking out the hardened melting resin molding from the mold, wherein the heating furnace is set at the temperature condition based on the resin material with a high melting temperature, and the molding is performed by lowering into the temperature range suitable for a resin material with a low melting temperature before the forming step as for the mold molding a resin material with a low melting temperature, to thereby enable the slush casting by resin materials having different melting temperatures.
