- Proper design of the rigging system is critical to provide
for uniform, controlled metal flow into the mold.
==> Non-uniform, long path, and/or slow metal flow may produce unfilled
sections or solidification shrinkage in the casting.
==> Excessively rapid metal flow or metal
splashing will cause mold/core erosion and oxidation of the steel, producing non-metallic
inclusions in the casting.
- The pintle socket casting is rigged with a side sprue
connected to four runners feeding into four ingates located around the base of the large
bowl.
==> The rigging is
illustrated in the drawing to the right.
