Any wax that runs out of the mould is usually recovered and reused. [11] Burnout preheating: The mould is then subjected to a burnout, which heats the mould to between 870 °C and 1095 °C to remove any moisture and residual wax, and to sinter the mould. Sometimes this heating is also used to preheat the mould before pouring, but other times ...
In addition to the main aspects of casting production – filling, crystallization, and porosity prediction, ProCAST is capable of predicting the occurrence of deformations and residual stresses in the casting and can be used to analyze processes such as core making, centrifugal casting, lost wax casting, continuous casting.

Lost-wax casting – also called investment casting, precision casting, or cire perdue (French: [siʁ pɛʁdy]; borrowed from French) [1] – is the process by which a duplicate sculpture (often a metal, such as silver, gold, brass, or bronze) is cast from an original sculpture. Intricate works can be achieved by this method.
The direct molding method is to make the wax material into the same wax mold as the casting by hand or other tools; the indirect molding method is to make the wax mold through the mold. The direct molding method requires craftsmen to have a high technical level, otherwise the quality of castings cannot be guaranteed.
A model can be made from any solid material, such as wax, [8] wood, or metal, and after taking a cast of the model (a process called investment) the model is removed from the mould. One method of forming a mould is by the Cire perdue or "lost wax" method. Using this method, a model can be made from wax and after investment the wax can be ...
Evaporative-pattern casting is a type of casting process that uses a pattern made from a material that will evaporate when the molten metal is poured into the molding cavity. The most common evaporative-pattern material used is polystyrene foam. [1] The two major evaporative-pattern casting processes are: [1] Lost-foam casting; Full-mold casting
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
Loose moissanite stones may be placed directly into wax ring moulds for lost-wax casting, as can diamond, [84] as moissanite remains undamaged by temperatures up to 1,800 °C (3,270 °F). Moissanite has become popular as a diamond substitute, and may be misidentified as diamond, since its thermal conductivity is closer to diamond than any other ...
