Abstract

PURPOSE: A method for casting a hollow precious metal article is provided to create a wide inner space in the precious metal article and reduce material cost by injecting molten candle into the rubber mold after inputting pre-molded gypsum into a rubber mold, thereby performing gypsum mold operation using hardened candle that envelops the pre-molded gypsum. CONSTITUTION: The method comprises the steps of molding the gypsum having a shape corresponding to a desired precious metal article by injecting gypsum into a mold and heating the injected gypsum; putting the molded gypsum into a cavity having a shape of the desired precious metal article formed on a rubber mold, and injecting molten candle into the cavity through a candle injection port so that hardened candle envelopes the gypsum; putting the hardened candle encircling a core material of the gypsum into a gypsum mold, and injecting molten gold or silver into the hardened candle containing the gypsum so that molten gold or silver is hardened on the gypsum by melting the candle that covers the gypsum; and manufacturing a hollow precious metal article by discharging the gypsum contained in the hardened gold or silver to the outside using high pressure air generated by a pump and supplied from a nozzle.
