Shell Mold Casting

Shell mold casting is a variation of the more traditional sand casting process. Shell mold casting can be done in three ways.

First, the pattern can be placed in a layer of dry sand and then covered with wet sand before compacting to remove any air pockets. This is called dry shell molding.

Second, the pattern can be coated in liquid latex or rubber before being cast into wet sand. This creates a liquid shell mold.

Third, the pattern can be dipped in liquid latex or rubber before being cast into wet sand. This creates a liquid-liquid shell mold that is very flexible and durable for repeated use.
