Shell mold casting

This process provides workers with numerous operating advantages and no environmental pollution.A heated metal pattern is covered with a mixture of sand and thermoset plastic. This causes a skin of sand mixture to adhere to the pattern. This skin is removed from the pattern to form the "shell mold". The two halves of the shell mold are secured together and the metal is poured in the shell to form the part. Once the metal solidifies, the shell is broken.
The materials that can be used with this process are cast irons, and aluminum and copper alloys. Typical parts made with this process are connecting rods, gear housings, lever arms
