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. Investment casting is so named because the process invests (surrounds) the pattern with refractory material to make a mould, and a molten substance is cast into the ...
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.
Ceramic mold casting, also known ambiguously as ceramic molding, [1] is a group of metal casting processes that use ceramics as the mold material. It is a combination of plaster mold casting and investment casting. [2] [3] There are two types of ceramic mold casting: the Shaw process and the Unicast process. [4]
Investment casting derives its name from the fact that the pattern is invested, or surrounded, with a refractory material. The wax patterns require extreme care for they are not strong enough to withstand forces encountered during the mold making. One advantage of investment casting is that the wax can be reused. [5]
Investment casting is a metallurgical processing technique in which a wax form is fabricated and used as a template for a ceramic mold. A ceramic mold is poured around the wax form and solidifies, the wax form is melted out of the ceramic mold, and molten metal is poured into the void left by the wax.
It is widely considered that the maximum weight of an investment casting (also known as Lost Wax Casting) is 10 kg. [4] Strudyna's largest tensile casting is the SRS Structural Tie Rod Fork at 66.9 kg. Strudyna's tensile castings are known for the high standards of 'Passivation’ process.
