    摘要： The present invention provides a process for producing a multilayer molded article which includes supplying at least one piece of a skin material having a desired shape and a resin melt between unclosed upper and lower molds and closing the molds to form a multilayer molded article including the thermoplastic resin and the skin material which covers only a desired part of the article, wherein the resin melt is supplied at or near a center area of a rear face of the skin material, or wherein after the skin material is lifted to a position at which the skin material contacts a cavity surface of the upper mold by a vertically movable rod or bar which is positioned at a part of the lower mold on which the skin material is placed, the resin melt is supplied between the upper and lower molds and the rod or bar is returned to a determined position at least before the molding is completed. This process economically produces a multilayer molded article in which the skin material covers the desired part of the article without displacement and which has a good feeling.

    摘要： A multilayer molded article includes a resin body and skin material with good quality and is produced by a process which includes the steps of: (a) supplying a skin material between a male mold and a female mold which are attached to a clamping mechanism, (b) starting closing of the male and female molds, and supplying a resin melt for the resin body between the skin material and the male or female mold while temporarily stopping the closing action of the mold or adjusting a closing rate at 30 mm/sec. or less when a cavity clearance between the molds is in the range between (C+100) mm and (C+5) mm (wherein C is the cavity clearance when the molding is finished), and (c) further closing the molds to the cavity clearance of C to finish the molding.
