Investment or lost wax casting can be a versatile but ancient process, it can be familiar with manufacture hundreds of parts ranging from turbocharger wheels to driver heads, from electronic boxes to hip replacement implants.

The, though heavily dependent on aerospace and defence outlets, has expanded in order to meet a widening array of applications.
Modern investment casting has its roots in the heavy demands in the World war ii, but it was the adoption of jet propulsion for military as well as civilian aircraft that stimulated the transformation on the ancient craft of lost wax casting into one of the foremost techniques of modern industry.

Investment casting expanded greatly worldwide throughout the 1980s, in particular to fulfill growing demands for aircraft engine and airframe parts. Today, investment casting can be a leading part of the foundry industry, with investment castings now comprising 15% by price of all cast metal production in england.

It happens to be the modernisation associated with an ancient art.

Lost wax casting has been employed for at least six millennia for sculpture and jewellery. About 100 years ago, dental inlays and, later, surgical implants were made with all the technique. World War two accelerated the demand for new technology and after that with the introduction of gas turbines for military aircraft propulsion transformed the traditional craft in a modern metal-forming process.

Turbine blades and vanes were required to withstand higher temperatures as designers increased engine efficiency by raising inlet gas temperatures. Modern technology has certainly benefited from an exceptionally old and ancient metal casting process. The lost wax casting technique eventually triggered the introduction of this process
referred to as Lost Foam Casting. What exactly is Lost Foam Casting?

Lost foam casting or (LFC) is a term metal casting method that uses expendable foam patterns to generate castings. Lost foam casting utilises a foam pattern which remains within the mould during metal pouring. The froth pattern is replaced by molten metal,
producing the casting.

The usage of foam patterns for metal casting was patented by H.F. Shroyer during then year of 1958. In Shroyer’s patent, a pattern was machined from the block of expanded polystyrene (EPS) and sustained by bonded sand during pouring. This process is termed the entire mould process.

While using full mould process, the pattern is often machined from an EPS block and it’s accustomed to make large, one-of-a kind castings. The complete mould process was originally known as the lost foam process. However, current patents have required that the generic term for your process is termed full mould.

It was not until 1964 when, M.C. Fleming’s used unbonded dry silica sand using the process. It is known today as lost foam casting (LFC). With LFC, the foam pattern is moulded from polystyrene beads. LFC is differentiated from the full mould method through unbonded sand (LFC) as opposed to
bonded sand (full mould process).

Foam casting techniques are already known as by a variety of generic and proprietary names. Of these are lost foam, evaporative pattern casting, evaporative foam casting, full mould, Styrocast, Foamcast, Styrocast, and foam vaporization casting.

These terms have ended in much confusion in regards to the process for your design engineer, casting user and casting producer. The lost foam process has even been adopted by people who practice ale home hobby foundry work, it possesses a not too difficult & inexpensive technique of producing metal castings outdoors foundry.
