The Investment casting process begins with producing a heat disposable pattern. This is accomplished by injecting wax into a metal die. A pattern must be moulded for every casting. These patterns are assembled into a cluster (or tree) and are then coated with various liquid ceramic refractory to form a ceramic shell. The wax is then melted out of the ceramic shell. Any number of different alloys can be cast into the ceramic mould. After cooling, the ceramic shell is removed and the castings are cleaned. The investment casting process maintains typical dimensional accuracy of +/-.005″ per inch, with a surface finish of 125 RMS or better.
