Abstract
A method for molding a sheet blow molding, wherein a board member as a core of the sheet blow molding is placed between a pair of thermoplastic sheets facing each other and separated by a predetermined distance. Opposite ends of the sheets are clamped by dampers so as to form clamped sheets with a closed space between the clamped sheets. The clamped sheets are heated by a heater and air is supplied to the closed space. The clamped sheets are pressed between molds so as to cover all outer surfaces of the board member and to be thermally bonded to the board member.
