A method for manufacturing automotive interior component parts, including the steps of: positioning a skin layer, having a back liner cushioning layer, on a mold surface of an upper mold with the cushioning layer facing downward; extruding a sheet of semi-molten thermoplastic resin material serving as a core layer directly onto a mold surface of a lower mold; clamping together the upper and the lower mold in such a manner that the core layer and the skin layer are bonded together with the cushioning layer interposed therebetween. Since the core material is sufficiently soft when it is bonded to the skin layer and the cushioning layer provides a buffer for the press pressure and a barrier against the infiltration of the soft core material, the skin layer is given with a very smooth surface even when it is made of porous material such as fabric. Additionally, since the core material is directly extruded onto a core surface, the pressure and the temperature involved the press forming process may be low.
