ABSTRACT OF THE DISCLOSURE The invention relates to a method of manufacturing a surface material made from different materials. A heat- resistant mold having its inner surface corresponding to the product to be produced, and a second mold to contain materials, are put together to form a molding chamber inside; and the materials of powder, paste of liquid thermoplastic resin materials are then placed in the molding chamber. In heating the chamber to form the surface materials, a partition is formed to divide the overall mold into a plurality of molding chambers leaving a certain gap against the inner surface of the mold. A groove is provided on the upper end of the partition and a small projection corresponding to the groove is made on the inner surface of the upper mold wall. Different kinds of resin materials are placed in the plurality of chambers and a resin body is placed in the groove of the partition. The upper mold and the material-containing mold are put together with the projection inserted into the resin body to form the surface materials in the molding chambers simultaneously; and the surface materials in the adjacent chambers are bonded together by the melting resin in the groove.
