    en.wikipedia.org/wiki/Lost-wax_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.

    en.wikipedia.org/wiki/Investment_casting

    The fragile wax patterns must withstand forces encountered during the mould making. Much of the wax used in investment casting can be reclaimed and reused. [2] Lost-foam casting is a modern form of investment casting that eliminates certain steps in the process.

    This alloy gave the gold-works a reddish hue within the final product and allowed further malleability post the casting process. Much of the gold and Tumbaga works of the Quimbaya are believed to have been cast with the lost wax technique, a form of casting that has been found throughout ancient civilisations as early as 4000 BCE.

    Dhokra (also spelt Dokra) is non–ferrous metal casting using the lost-wax casting technique. This sort of metal casting has been used in India for over 4,000 years and is still used. One of the earliest known lost wax artifacts is the dancing girl of Mohenjo-daro. [1]

    Passing from the core through the wax and projecting beyond are metal rods. The modelling being completed, called lost-wax casting, the outer covering which will form the mould has to be applied; this is a liquid formed of clay and plaster sufficiently thin to find its way into every detail of the wax model. Further coatings of liquid are ...

    Investment casting was invented in 4500–4000 BC in Southeast Asia [1] and carbon dating has established mining at Alderley Edge in Cheshire, UK, at 2280 to 1890 BC. [6] Ötzi the Iceman, a male dated from 3300 to 3200 BC, was found with an axe with a copper head 99.7% pure; high levels of arsenic in his hair suggest his involvement in copper ...

    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.
