A foam layer can be formed at a temperature at which the surface quality of a surface layer is not deteriorated, and a molding technique that is excellent in adhesiveness of a foam layer and a surface layer or/and a base member is developed. For the purpose of obtaining a resin molding composite, the present invention is characterized by a polyolefin resin molding composite comprising a surface layer and a foam layer, or a surface layer, a foam layer, and a base member, wherein the foam layer comprises a foam layer produced by fusion bonding thermoplastic expanded resin particles one another by molding, where the thermoplastic expanded resin particles comprises a core that is made of a crystalline thermoplastic resin and is in an expanded state and a polyethylene resin coat covering the core, and the surface layer comprises a thermoplastic synthetic resin having a melting point of 5&deg; C. or more higher than a melting point of polyethylene resin constituting the coat of the particles.

This invention relates to a cooling process suitable for foam molding of a synthetic resin and its cooling apparatus. Cooling water which is supplied into a flowing pressurized gas is turbulently jetted in the form of a mist into the overall area of respective chambers in a pair of molds. The mist, adhering uniformly to the overall walls of the molds remove latent heat from the mold surface, and consequently uniformly cool the entire mold. Further, a large quantity of steam generated from the mist as well as excess mist are forcibly discharged outside the chambers by a preferred suction means including a blower, etc., whereby the cooling effect on the walls of the molds is further enhanced.
