Mold Feature A

In Feature A, the narrow pocket between the bowl rim and the bracket flange would be produced by a thin plate extension on the sand mold.
That thin extension would be vulnerable to breakage because of its small cross-section.
The flange and bowl should be redesigned to eliminate the pocket and form a solid junction between the bowl rim and the flange.

This not only reduces the chance of mold breakage; it also increases the bending resistance of the flange.

Feature A does need to be changed
