OVERVIEW OF THE PRECISION CAST-INVESTMENT CASTING PROCESS

Precision Investment casting, often called lost wax casting, is regarded as a casting process to build near-net-shaped metal parts from almost any alloy. The most common use of investment casting in more recent history and has been the production preference of components requiring complex, especially thin-wall castings.

The investment casting process begins with fabrication of a sacrificial pattern with the same basic geometrical shape as the finished cast part. Patterns are normally made of investment casting wax that is injected into a metal wax injection die. Once a wax pattern is formed, it is assembled with other wax components to form a metal delivery system , called the gate and runner system. The entire wax assembly is then dipped in a ceramic slurry, covered with a sand stucco, and allowed to dry. The dipping and stuccoing process is repeated until a shell of ~6-8 mm is applied.

Once the ceramic has dried, the entire assembly is placed in a steam autoclave to remove most of the wax. After autoclaving, the remaining amount of wax that soaked into the ceramic shell is burned out in a furnace. At this point, all of the residual pattern and gating material is removed, and the ceramic mold remains. The mold is then preheated to a specific temperature and filled with molten metal, creating the metal casting. Once the casting has cooled sufficiently, the mold shell is chipped away from the casting. Next, the gates and runners are cut from the casting, and final postprocessing (shot blasting, machining, polishing) is done to finish the casting.
