An intermediate mold having a molding part is provided, and the SMC material is placed on the molding part of the upper surface of the intermediate mold and the molding part of the lower mold, respectively, and then the upper mold and the intermediate mold are lowered to form the upper mold. The intermediate mold, the intermediate mold and the lower mold are each clamped, and the SMC material is pressure molded to form two FRPs at the same time.
Since the molded product is obtained, two FRP molded products of the same or different shapes can be manufactured simultaneously within the same planar space as compared to the conventional method of manufacturing one FRP molded product in one operation, and Compared to the case where two FRP molded products are manufactured in parallel, productivity can be improved without increasing the work space. In addition, by lowering the upper mold and the intermediate mold together with the SMC cable sandwiched between them, the SMG can be used until the upper mold and the intermediate mold are clamped.
Materials can be reliably held in place.
