Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the cost of a molded article and to improve the quality of the molded article. SOLUTION: A molding material is supplied to a first mold in a molten state and cooled in the first mold to be molded into a preliminary molded article. The preliminary molded article is taken out of the first mold to be supplied to a second mold, wherein it is deformed to be molded into a final molded article. The weight of the preliminary molded article can be sufficiently adjusted, and also properties of the surface can be made sufficiently satisfactory. Thus, the accuracies of dimension and surface required for the final molded article can be sufficiently achieved. COPYRIGHT: (C)2003,JPO
