PURPOSE:To perform economically titled molding without a wooden master mold by disposing rubber members to the top and bottom of a master mold formed by depositing a metallic layer by vacuum evaporation on the surface of a molding made of a synthetic resin and forming rubber molds on the opposed surfaces of the rubber members by a press. CONSTITUTION:A metallic layer 3 consisting of a thick film is stuck on a molding 1 made of an injection-molded synthetic resin in a vacuum evaporation vessel 2 to manufacture a master mold M. Rubber members 4, 4 are disposed to the top and bottom parts of the mold M and are pressurized from the upper and lower directions of the members 4, 4 by press machines 5, 5 to transfer and mold the mold M on the opposed surfaces 6, 6 of the members 4, 4, thereby forming temporally rubber molds 7, 7 formed with recessed parts 8, 8. The normal rubber molds 10, 10 obtd. by correcting the dissidence, etc. of the molds 7, 7 and the mold M, etc. are disposed in a molding machine and thereafter a molten metal is forced into the mold through a runner. The metallic molding A having exactly the same shape and size as the shape and size of the above-described molding 1 is thus molded.
