• The sand mold cannot provide the needed dimensional and surface finish. Sawing and grinding operations are required to remove the rigging and will introduce variations in the finished appearance.

• The lower thermal conductivity of the sand mold slows the solidification in the casting, producing a larger grain size and lower strength.

• The extra rigging (risers) required for sand castings will require additional metal feedstock and will reduce the metal yield.
