Abstract:
A method of manufacturing a thermoplastic resin molded article having a hollow portion includes setting a molded article (A) premolded from a thermoplastic resin in a first die, forming a melted thermoplastic resin plate (B) in a shape along an inner surface of a second die facing the first die by being attached to the inner surface of the second die by vacuum pressure, welding the thermoplastic resin plate (B) and the molded article (A) only in a predetermined region by mold-clamping the first die and the second die, and forming at least part of an unwelded region as a hollow portion.
