In Investment Casting,Casting patterns are molded by the injection of a special wax into a metal die.  The patterns are assembled into a cluster around a wax runner system. The 'tree' of patterns is then coated with 8-10 layers of a refractory material. The assembly is heated to remove the wax.  The hot mold is cast, and when cool, the mold material is removed by impact, vibration, grit blasting, high pressure water blasting or chemical dissolution leaving the castings, which are then removed from the runner system.
