Lost wax casting now called revestment precision casting, is a less cutting or no cutting casting process, is an excellent technology in foundry industry, its application is very extensive. It is not only applicable to the various types, various kinds of alloy casting, and produce the casting dimension accuracy and surface quality is higher than other casting method, even other casting method is difficult to cast the complex, high temperature resistant, not easy machining castings, all can use revestment precision casting wrought.
Revestment precision casting is developed on the basis of ancient lost wax casting. As ancient civilizations, China is the use of this technology is one of the early, long centuries BC, the ancient Chinese working people created this kind of lost wax casting technology, used for casting with ?
