Filling and solidification of aluminum alloy drain pipe for automobile in tilting casting and in gravity casting were predicted by the Anycasting software. Simulated results were analyzed quantitatively. The results reveal that

for thin-walled drain pie with complex structure and large ratio of length via thickness

compared with gravity casting

tilting casting exhibits the features of lower and smooth filling velocity

uniform distribution of filling pressure from bottom to top

desirable exhausting effects and lower entrapped-gas and shrinkage porosity tendency

greatly improving the quality of the parts and production yield.
