METHOD OF MANUFACTURING LAMINATED MOLDING

WIPO Patent Application WO/1993/001929

A1

A method of manufacturing laminated molding using a skin material preliminarily shaping device having a male mold and a female mold and a laminate molding device, comprising: (1) a process of preliminarily shaping a skin material; (2) a process of transferring the skin material to the molding device in a state where the skin material thus preliminarily shaped is held by the female mold or the male mold for preliminarily shaping, and fitting and setting the same into a male mold or a female mold for molding; (3) a process of supplying thermoplastic resin to serve as a core material layer in a molten state, and pressurizing, cooling and shaping the same; and (4) a process of opening the male and female molds for molding and taking out the laminated molding. Positioning of the skin material can be accurately carried out with a simplified method and even a deeply drawn laminated molding having a complicated shape in three dimensions can be given an outstanding appearance without damage to the skin material.
