摘要 PURPOSE:To shorten the manufacturing time of resin-molded product provided with a plurality of layers and reduce the manufacturing cost of the same by a method wherein the resin powder is loaded into a heated mold to adhere it to a forming groove while a removing process of excessive resin powder and the adhering process of the same are effected at least one time by using different resin powder. CONSTITUTION:The PVC resin powder, becoming the surface skin 4 of the product, is loaded into a bottom force 12 and a part of it is molten by heat to obtain a given thickness while the bottom force 12 is converted to remove the excessive PVC resin powder.
