ABSTRACT:
Methods for manufacturing multilayer moldings using a mold including a pair of male and female mold pieces for manufacturing a multilayer molding in which a part of its thermoplastic resin substrate surface is partially laminated with a shin material. Either the male or the female mold piece has a mold surface provided with a molten resin feeding path opening inside an area where the skin material is placed and at least one dent into which a part of or the whole skin material fringing end can be inserted, at a part of or the whole position corresponding to a fringe of the skin material to be laminated and a block to be fitted into the dent. The block is fitted into the dent so that the skin material fringing end inserted into the dent is sandwiched and fixed between an inner wall of the dent and the block and at the same time an upper surface of the block can form an even mold surface with the mold surface surrounding the dent.
