Production of instrument panel

Abstract

Abstract PURPOSE: A frame with poor adherability is placed on a preformed plastic film set in a mold and a urethane foam is poured into the cavity between the film and frame and foamed, thereby forming instrument panels of good quality in simple precesses. CONSTITUTION: Surface material 1 that is preformed through vacuum forming is set on bottom mold 2, frame 3 of poly propylene composite is placed thereon and they are fixed with top mold 4. Then a urethane foam is poured into the cavity between the surface material and the frame and foamed. At this time, the frame of polypropylene composite of poor adherability with urethane foam 5 contacts with surface material 1 of vinyl chloride resin directly at the surface 7 of unnecessary part 6 in the surface material. Then, frame on which pads are partially formed is taken out of the mold and the unnecessary part 6 is cut off with cutter 8 and readily released from frame 3 COPYRIGHT: (C)1979,JPO&Japio
