The main casting defect in thin-wall big plane casting is choking air hole and bubble. The defect led by choking air hole reached 70 per cent. This kind of defect has caused great impact on casting quality, production efficiency and production cost. Several methods to solve the defect of choking air hole in thin-wall big plane casting,such as pouring temperature,core outgassing and pouring system have been introduced.
