Shell Room
Shell room is 400 square meters (4000 sf) The second step in the investment casting process is the building of a ceramic shell around the wax pattern. This process is accomplished by first cleaning the parts in a three-step dip process, ten coating the wax part with a ceramic slurry, followed by broadcasting sand onto the wet surface. Once a part is coated in this fashion, it must dry completely, […]
