Shell molding casting process is also called pre-coated resin sand casting process, hot shell molding castings or core casting process. The main molding material is the pre-coated phenolic resin sand, which is more expensive than green sand and furan resin sand. Moreover, this sand can not be recycle used.

Compared to the normal sand casting process, shell mold casting process offers better surface finish, better dimensional tolerances, and higher throughput due to reduced cycle times. The materials that can be used with this process are cast irons, and aluminum and copper alloys. The shell molding process produces cost savings solutions for difficult shapes, pressure vessels, weight sensitive parts, and castings requiring superior surface finishes.
