Abstract: In a simultaneous molding to one piece, at a time of heat molding of a surface skin material 3, after an edge part of the surface skin material 3 is folded back to an inside direction of the mold pattern and is formed up a folded back part 7 along a mold pattern for folding back 6 which is placed as in a manner of projecting from an opening edge 2b of a cavity face 2a toward the inside direction of the mold pattern, the mold pattern for folding back 6 is removed, and then at a time of the expansion molding, one face 7a of the folded back part 7 is melt united to one piece with a back face 5b of the cellular molded article in a mold pattern 5, and at the same time, a folded returning part 8, which is in a state that an outer edge part of the surface skin material 3 is folded returning toward an outside direction of the mold pattern from a tip 7c of this folded back part 7, is pressed so as to pile on the other face 7b of the above-mentioned folded back part 7.

Abstract: A decorative member material, of which interior trim material is light weight, comfortable touch and can be used in spite of its low strength, is provided.

Abstract: This invention relates to a method for producing cellular molded article in mold pattern of synthetic resin having surface skin which is used, for example, as an automobile interior trim material or the like and a mold pattern for producing thereof. This invention aims to provide a method for producing cellular molded article of synthetic resin having surface skin which has good production efficiency and which comprises that cellular molded article of synthetic resin obtained by cellular molding of expanded beads in which poor melt bonding does not occur and thermoplastic resin skin material united with this cellular molded article of synthetic resin which has excellent appearance without residing beads pattern on its surface, and a mold used for producing thereof.
