Abstract

Based on the AlSi12 Fe filter-cavity castings

through analysis of the forming test and the numerical simulation

effects of the initial cavity gas pressure on mold filling during the vacuum die casting process were investigated.The results reveal that it is more difficult to form the castings with the decrease of the initial cavity gas pressure and increasing in drawing vacuum time.
