Orientation in the Mold

In mold design for castings, the orientation of the part in the mold is an important factor in producing a sound casting.

Casting defects (porosity, inclusions), when they occur, tend to rise and segregate in the cope or upper section of gravity castings.
Defects should also be minimized in any machined sections or surfaces.

Machined surfaces and critical features should be designed so that are molded in the drag or the lower section of the casting.
