PURPOSE: A method for manufacturing a metallic matrix for processing is provided which forms 18K or 14K gold into a final film having a desired thickness without using of an existing plating method so that the finally manufactured metallic matrix is easily machined, and the metallic matrix manufactured by the method is provided. CONSTITUTION: The method for manufacturing a metallic matrix for processing comprises a first step of positioning a silver material having a certain size at the center in the corresponding first mold; a second step of preheating the silver material so that the surface of the silver material is partially solidified; a third step of injecting molten gold into the mold so that the molten gold envelops the outer surface of the silver material; a fourth step of cooling the injected molten gold so that the molten gold is impregnated and bonded to the surface of the silver material; a fifth step of separating the bonded material from the first mold after annealing a bonded material of the fourth step; a sixth step of heating the alloy film covered bonded material put in the second mold after covering an alloy film comprising pure gold on the surface of the separated bonded material, and putting it in the corresponding second mold; a seventh step of cooling the material so that the alloy film is bonded onto the outer surface of the bonded material after heating; and an eighth step of separating it from the second mold after annealing the bonded material of the seventh step.
