Abstract
PURPOSE: To complete pouring during holding of preheating temperature, prevent defects owing to gas expansion in a ceramic core and improve quality by disposing said core into the mold of the portion of a casting requiring high quality.
CONSTITUTION: A ceramic core 7 having beforehand been heated to a high temperature is set only in the core of the portion of a casting requiring dimensional accuracy and surface smoothness. The mold 8 and core 9 of the portions other than this are of ordinary molds. Next, while the ceramic core 7 is holding a heated state, pouring is completed and the rate of pouring of a cavity 10 is adjusted, whereby the ascending speed of the molten metal is decreased and the adsorbed moisture or inflammable impurities of the core 7 are perfectly discharged.
