Abstract: PURPOSE:To obtain an in-mold transfer board that can be manufactured by an easy process and has excellent appearances by slowing problems in which a process in conventional fabrication or the like is complicated, or in the case of a molding, defects of burnings, sinks and the like occur in a manufacture of the in-mold transfer board of a refrigerator door, and in molds. CONSTITUTION:On the circumference of a gate 9 of the other mold 8, a radiator 10 is disposed which comprises an alloy of copper-beryllium with good thermal conductivity so that the temperature of molten synthetic resin 14 to be injected into mold from the gate 9 is diffusion-cooled by the radiator 10. Thus, the occurrence of defects of burnings, sinks and the like, and the peeling of a pattern layer from the resin molding can be prevented, thereby obtaining a good refrigerator door of large size and with beautiful appearances.
