手作業であり、歳事的な方法が望まれている。[Prior Art and Problems Therewith] It is known that FRP molded products are advantageous products that can be molded at once by incorporating various accessory parts at the same time, reducing the number of manufacturing steps. However, when the shape becomes complex, it cannot be formed all at once, and post-processing is required, as well as inefficient manual work. For example, in parts used as automobile exterior panels, soft PVC is glued to the outer periphery in a post-process to prevent interference with the podium and damage, and parts used as automobile interior materials. For parts, protectors are attached to eliminate gaps with interior materials and to protect the outer periphery, but this installation process is still a manual post-processing process, and a routine method is desired.
