Zusammenfassung:PURPOSE:To prevent solidification of molten metal at early time by setting insert part just above the molten metal level, pressurizing the molten metal in a sprue to fill up the molten metal into cavity in the insert part and solidifying. CONSTITUTION:Joining part 9 as the insert part in a pipe member 7 of the member bonded to the casting product with the insert, is set just above the molten metal level 10 after casting. After casting the molten metal 14 from the sprue 4, the molten metal 14 in the sprue 4 is pressurized by using pressurizing unit 15. Then, the molten metal is filled up into the cavity 3a in the insert part 9 and solidified. By this method, the insert having sufficient bonded force and air-tightness can be formed with low pressure.
