  • Method for manufacturing foam molded body
    Patent number: 10940620
    Abstract: A method for manufacturing a foam molded body which can allow the foam resin sheet to follow the shape of the cavity of the mold with high accuracy even when the thickness of the foam resin sheet is thick. The method includes an arranging step to arrange one sheet of a foam resin sheet between first and second molds, the foam resin sheet being formed by extruding and dangling a molten foam resin from a slit; and an expanding step to expand the foam resin sheet by subjecting the foam resin sheet to a reduced pressure suction.
