Investment Casting (or) Lost Wax Method

Investment casting, also called lost wax casting, is regarded as a precision casting process to fabricate close-to-final shape metal parts from almost any alloy metal. The most common use of lost wax casting has been the production of components requiring complex, thin-wall castings.

The precision 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 produced, 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 (1/4-3/8 in) is applied.

After 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) is done to finish the casting.

Investment Casting is generally more expensive than it's associated metal casting methods of "sand casting", but can produce complicated shapes that require little rework or machining. Investment casting is used in many advanced technical industries such as Aerospace, Power Generation, Oil & Gas, Military & Defence, Medical, Commercial and Automotive.

Applications:

Water solution industry for pumps, Valves, Pipe Fittings)

Automotive

Marine and Oil, gas

Machinery

Power Generation

Energy

Other Mechanical part Castings
