Precision casting refers to the use of fusible materials made of fusible model in some special refractory coating layer on the coating, after drying and hardening to form a whole shell, and then steam or hot water from the shell in the melt model, then put the shell into the sand box, dry sand filling in the other around, finally casting into the baking furnace after calcination, cast or shell after roasting, the pouring of molten metal and casting. Casting the product precision, complex, close to the final shape of the part, not processed or rarely processing is used directly, is a near net form of advanced technology, is an excellent technology for foundry industry, its application is very extensive. It is not only suitable for the casting of various types, all kinds of alloy, and the production of casting dimension accuracy and surface quality than other casting methods must be high, and even other casting methods is difficult to cast the complex, high temperature and easy machining castings, can be used in precision casting cast. At present, the world of casting forming process of rapid development and wide application, from the current situation, the future development trend of the technology of the future is casting products more and more close to the parts, the traditional casting only as a blank, can not adapt to the rapid market response. The complexity and quality of parts and components are getting higher and higher, and the means of R & D are becoming more and more intensive. Professional collaboration is beginning to show, and the application of CAD, CAM and CAE has become the main technology of the development of parts and components. From the analysis of the present development situation, the application of investment casting technology is very extensive, and the future prospect of investment casting technology is promising.
