Zusammenfassung:A manufacturing method of molding goods using polyurethane is provided to manufacture easily products of uniform quality by spraying raw material on molds. A manufacturing method of molding goods using polyurethane comprises a step of forming a sheet having 1~2mm of thickness by applying soft polyurethane on a mold in spraying way(S100); a step of forming a core having 2~4mm thickness by lowering the top mold(S200); a step of preparing a foaming forming that lowering the top mold up to proper height of the bottom mold and thus holding it(S300); and a step of completing the foaming forming that filling the sheet and the core and thus forming a cushion layer having 6~9mm thickness between them.
