Solidification Model
Approach B --
Riser on the Foot
  • In Approach B, a riser is placed at the foot of the plate to feed metal into that hot section.
  • Computer solidification modeling shows that the riser “pulls” the hot spot out of the foot of the plate into the riser, producing a sound casting.

 

The riser at the foot is a good method to eliminate shrinkage.
Go on to the next design issue.
