| Abstract: | An approach of modeling on the mold filling process for lost foam casting (LFC) was proposed according to the characteristics of LFC. Artificial neural network technique was applied to calculate the locations of metal front at time intervals. The results of simulations and experiments are consistent, both in filling pattern and sequence. |
