In a method for molding a laminated assembly comprising a resin core member, and a surface skin member either partly or entirely placed over the surface of the resin core member, the dimensional precision of a part of the surface skin member involving a high rate of extension is improved, and the cushioning property and the surface quality of this part are avoided from being impaired. An approximately molded portion is defined in a part of the surface skin member involving a relatively high rate of extension during the vacuum molding process using a vacuum molding die assembly, and the thus molded surface skin member is mounted on the upper die for mold press forming with a gap defined between the approximately molded portion or an unmolded portion and the associated die surface. During the mold press forming process, the pressure of the semi-molten resin material molds the surface skin member into its final shape so that the molding precision of the part of the surface skin member involving a high rate of extension can be improved. In particular, when the surface skin member is lined with a foamed lining layer, damage to the foamed lining layer of the surface skin member during the process of mold press forming is minimized.

[ What we claim is:] [1.] A method for molding a laminated assembly comprising the steps of:molding a first portion of a surface skin member generally into a prescribed shape and a second portion of said surface skin member into an approximation of its final prescribed shape, by using a vacuum molding die assembly;mounting said surface skin member on an upper die such that a gap is defined between said second portion and an associated surface of said upper die;supplying softened resin material for a resin core member over a lower die; andclosing said upper die over said lower die thereby to (1) mold said resin core member into a prescribed shape, (2) attach integrally said surface skin member to said resin core member, and (3) form said second portion into its final prescribed shape;wherein said second portion of said surface skin member is subject to a high rate of extension when placed over a surface of said resin core member, and said portion of said surface skin member molded into said approximation of its final prescribed shape consists of a securing groove defined in said surface skin member which is adapted to receive a peripheral portion of an additional sheet member placed over said surface skin member.
