- Proper design (location, number, and size) of the risers
is critical to prevent shrinkage voids in the casting.
- The risers must provide metal feed into all the sections
of the casting.
- Ideally, all sections of the casting will receive
sufficient feed metal to solidify without shrinkage voids. The risers will be the last to
solidify.
- The drawing to the right shows the 10 risers feeding
into the top plate of the pintle socket.
