The casting process of squeezing casting suspension bracket was analyzed by the MagmaSoft

and the optimized processing parameters were presented.The simulation result shows that the un-even wall-thickness can cause the hot spot

and it is difficult to feed and sequential solidification at pressure because of far away ingate

which are responsible for the formation of shrinkage porosity（holes）in the suspension bracket.Through squeezing large-thick location

such as local squeezing feeding

forced cooling or adding chilling block to modify the solidification order of think-large location of the bracket

the shrinkage porosity（or holes）can be eliminated by realizing sequential solidification.Aiming at suspension bracket

through modifying ingate size

shrinkage porosity can be eliminated

which is verified by the practical production.
