THE METAL INFILTRATION CASTING PRODUCT AND METHOD FOR MANUFACTURING METAL INFILTRATION CASTING PRODUCT USING CARBON MOLD

摘要

PURPOSE: A metal infiltration casting product and a method for manufacturing metal infiltration casting product using carbon mold are provided to productivity of a product having a complex three dimensional structure by reducing evaporating a carbon mold to carbon monoxide or carbon dioxide under oxidizing atmosphere. CONSTITUTION: A method for manufacturing a metal infiltration casting product comprise next steps. A raw material of a metal impregnation die casting product(P) is melted. Molten metal is filled in a cavity located in a carbon mold. The carbon mold is eliminated in order to form a metal impregnation die casting product. An oxide layer included in the metal impregnation die casting product is reduced and removed after a mold removing step. The molten metal flows in the cavity using gravity under vacuum atmosphere and mechanically pressurized to be guided in the molten metal. The molten metal is pressurized by the pressure offered from inert gas.
