| The design features (holes, ribs, pockets,
flanges, etc.) on the component are produced by duplication of the features in the molds
and cores |
In designing for large castings in sand
molds, it is important to review the design to eliminate or change those features that
require thin and/or long sections in the sand molds/cores.
Thin/long mold features are fragile and can break
during mold assembly and/or pouring.
The casting engineer should consult with the OEM design
engineer to determine what features can be modified for improved castability without
negative impact on component functionality or performance. |
