PROBLEM TO BE SOLVED: To accurately evaluate the strength by estimating the plate thickness change due to press molding and penetration into weld bead sections. SOLUTION: A manufacturing method comprises a process for manufacturing a vacuum molded product 1 formed by vacuum molding a resin plate composed of thermoplastic resin into the given shape and a process for butting another resin material 2 composed of thermoplastic resin with the vacuum molded product 1 and thermowelding a resin welding bar 3 composed of thermoplastic resin on a butting section. In that case, the reduction of plate thickness at the time of press molding an actual part can be simulated by vacuum molding a resin plate, and also penetration of a welded metal into weld bead sections at the time of welding the actual part can be simulated by using the resin welding bar 3 and carrying out the thermowelding. |
