SCZY LTD is specialized in Lost Wax Casting for different materials, normally we do Stainless Steel Casting, Carbon Steel Casting, Brass Casting, as well as other Special Alloy Casting, etc . For lost Wax Casting , we also call it Investment Casting, which is a production process in ancient China. In modern times, it is still the method used to bring out the finest details in metalwork. Such products are often difficult to manufacture due to their cumbersome design. The lost wax method enables any metal to completely and faithfully reproduce its wax pattern. Therefore, this method is still widely used in fields such as sculpture, jewelry processing, dentistry and industrial restoration.

The biggest advantage of investment casting Precision Casting is that due to the high dimensional accuracy and surface finish of Investment Castings, machining work can be reduced, and only a small amount of machining allowance can be left on parts with higher requirements, and even some castings Only the grinding and polishing allowance is left, and it can be used without machining. It can be seen that the investment casting method can save a lot of machine tool equipment and processing man-hours, and can greatly save metal raw materials.
Another advantage of the investment casting method is that it can precision cast complex castings of various alloys, especially high-temperature alloy castings. For example, the blades of jet engines, whose streamlined outline and inner cavity for cooling, can hardly be formed by mechanical processing technology. Production by investment casting technology can not only achieve mass production, but also ensure the consistency of castings, and avoid the stress concentration of residual knife lines after machining.

Our country began to apply investment casting to industrial production in the 1950s and 1960s. Since then, this advanced precision casting technology has been greatly developed, and has been widely used in manufacturing industries such as aviation, automobiles, machine tools, ships, internal combustion engines, gas turbines, telecommunication instruments, weapons, medical equipment, and knives as well as some arts and crafts.
