  • Method for manufacturing hollow molded article and apparatus for molding hollow molded article
    Patent number: 10723061
    Abstract: While naturally suctioning air between a first thermoplastic resin sheet and a second thermoplastic resin sheet from a fluid passage formed in a first thermoplastic resin sheet, the first thermoplastic resin sheet is subjected to vacuum-molding by a first vacuum molding die, a first shaping section is formed in the first thermoplastic resin sheet by a molded section of the first vacuum molding die, the second thermoplastic resin sheet is subjected to vacuum-molding by a second vacuum molding die, a second shaping section is formed in the second thermoplastic resin sheet by the molded section of the second vacuum molding die, and a hollow section is defined between the first thermoplastic resin sheet and the second thermoplastic resin sheet by the first shaping section and the second shaping section.
