Hiler Industries’ metal casting services utilize shell mold casting for all your ferrous casting needs. This process is very similar to standard sand casting, which uses disposable molds made of sand for forming liquid metal. However, the key difference between green sand casting and shell mold castings is the shell molds are thermally bonded with fine resin-coated sand to create a superior casting finish. This creates a thin-walled shell into which the molten metal is poured.
Because of the thin and rigid walls of the mold, this process is capable of producing precise castings. Many times this process is used to achieve tighter tolerances compared to a traditional green sand casting process.
