Lost wax method casting is now called investment casting, is a little cutting or no cutting casting process, is an excellent technology in the casting industry, its application is very wide. It is not only suitable for casting of various types and alloys, but also can produce castings with higher dimensional accuracy and surface quality than other casting methods.
