Investment casting (also called Lost Wax Casting), is one of the oldest metal-forming techniques. The castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. The process uses a wax pattern invested in a ceramic shell made with multiple dips in a ceramic slurry. When the shell dries, it is baked causing the wax to melt away. Then metal is poured into the empty shell. When the metal is solidified and cooled, the shell is broken away.
