| Abstract: | Effects of placing down-place bags behind ceramic foam filter in sand mold casting on filling mold ability have been studied based on the fluidity sample of aluminum liquid. Down-place bags have been also used to produce hot tearing circle thin wall castings. It is found that above methods can improve the filling mold ability, and its operation is simply. |
