Precision casting is compared with the traditional casting process in terms of a casting method. It can obtain relatively accurate shape and high precision casting. A common approach is: first, to make the required blank (can leave a very small margin or not allowance) electrode, and then use electrode corrosion die body, form a cavity. With casting method of casting wax, wax models for the original. Brush layers on the wax models on high-temperature liquid sand material. After get enough thickness to dry and then heat, make internal wax models of melting drop, get in line with the required blank cavity. Again in the hot metal casting in the mold, the outer peel off after curing, can obtain precise manufacturing of finished products.

Lost wax casting method now called revestment precision casting, is one of the less cutting or no cutting casting technology and casting industry is one of the excellent technology, its application is very broad. It not only applies to all types, all kinds of metal casting, and produce the casting dimension accuracy and surface quality is higher than other casting methods, or even other casting method is difficult to cast so complex, high temperature resistant, not easy to processing of castings, all can be used for investment casting precision casting.
