PURPOSE:To so constitute the title method that resin of a molding member injected previously and molten resin to be injected in the next time do not mix up with each other even if injection molding is performed by laminating the molten resin in order, by forming the next resin molded member of molten resin whose fusion temperature is lower than that of the resin molded member molded previously. CONSTITUTION:After a first cavity mold 20 has been broken by performing injection molding of a matrix material 10 by making use of opaque synthetic resin 10' such as a mixture of polycarbonate resin and ABS resin, a core molds 1 and second cavity mold 21 are clamped together by turning the core mold 11 by 180 deg.. A mounting material 20, which has been heated and molted at a temperature lower the fusion temperature of the matrix material 10, is injected within a cavity space 21a and the mounting material 20 is laminated unitarily on an external surface side of the matrix material 10 within the cavity space 21a. It is good when colorless or colored transparent or semitransparent synthetic resin such as methyl methacrylate resin is used as molding resin 20' and moreover the resin, whose fusion temperature of the extent of 230-240 deg.C which is lower than that of the molten resin 10' of the matrix material 10 relatively, is used. |
