摘要： PURPOSE:To produce merchandise of an intricate shape inexpensively by precision casting by forming a molten layer of a low m.p. metal and a molten layer of peastics on the surface of a prototype, and melting away the two layers formed by coating said layers further with a refractory material and casting a desired material into the cavity formed after the melting away. CONSTITUTION:A thin layer 12 of a molten layer of a low m.p. metal or its alloy is formed on one surface applied with the pattern of a prototype 11, and a molten layer of plastics such as wax, urea resin or the like is formed on the circumferential surface of the prototype including the layer 12. The prototype is removed and the formed two layers 12, 13 are coated with a refractory material 14 of a slurry or the like and are calcined, whereby a casting mold is manufactured. The two layers 12, 13 are melted away to form a cavity 16. A desired mold 17 is charged into the cavity 16 and is solidified, whereby a metallic mold or casting is obtained. The merchandise having various kinds of fine and stereoscopic surface patterns is adequately obtained by the above-mentioned method.
