Abstract:
A method of manufacturing an instrument panel which comprises a thermoplastic resin core material and a skin material integrally laminated to a surface of the resin core material, the instrument panel further comprising peripheral portions and a back portion, the instrument panel having brackets formed integrally with the resin core material in at least one of the peripheral portions and the back portion of the instrument panel; said brackets having at least one perforation, the method comprising the steps of:placing the skin material into a mold cavity between a pair of male and female molds designed such that an instrument panel shape having said brackets can be formed; one of said molds having a protrusion, in a bracket formation portion thereof, having a size corresponding to the at least one perforation and the other of said molds having a corresponding concavity for receiving the protrusion,feeding a melt thermoplastic resin to the cavity defined by the skin material and the pair of male and female molds, andforming the instrument panel having said brackets by press-molding the melt thermoplastic resin, whereby the skin material is laminated on said surface of the resin core material and said at least one perforation is formed as a result of fitting the protrusion with the corresponding concavity.
