Disclosed is a powder slush molding system that molds a slush skin by melting and adhering a powder resin material to an inner surface of a mold that is heated. The powder slush molding system includes a heating device, a rocking device, a cooling device, a demolding device, and a transfer device configured to transfer the mold between these devices. The cooling device includes a cooling bath and a table configured to turn upside down vertically above the cooling bath. The mold fixedly placed on an upper surface of the table faces the cooling bath side when the table is turned upside down. The table is configured to allow the mold to be placed also on a back surface of the table. The back surface faces upward when the table is turned upside down.
