ABSTRACT:
Methods are taught for manufacturing a press molded article (1) that comprises a profiled substrate layer (10) and a foamed layer (20). A substrate material (12) may be press molded with a foamable material (22) under pressure in order to join or attach the foamable material to the substrate material. In addition, a profile may be imparted to the substrate material during the press molding step, thereby forming the profiled substrate layer. After the press molding step has been completed, the foamable material is foamed and expanded, to thereby form the foamed layer. A skin material (32) optionally may be applied to the foamable layer before the press molding step. Optionally, embossed patterns may be imparted to the skin material during the press molding step, thereby forming an embossed skin layer (30) that is attached to the foamed layer.
