H1. The precision casting is a fusible model made of fusible materials,It is coated with several layers of special refractory coatings, which are dried and hardened to form a monolithic shell, and then melt the model from the shell with steam or hot water.The shell is then placed in a sandbox,dry sand around it.In the end, the cast type is placed in a roasting oven, which is baked in high temperature, and the cast or shell is roasting,the casting is made by pouring molten metal in it.
H2. The precise and complicated products obtained by investment casting precision casting,Close to the final shape, can not machining or rarely used directly, is a kind of advanced net-shape forming technology, is an excellent casting industry technology, its application is very broad.It is not only suitable for casting of various kinds and alloys,And produce the casting dimension accuracy and surface quality of the higher than other casting methods, or even other casting method is difficult to cast the complex, high temperature resistant, not easy machining castings, all can use revestment precision casting wrought.
H3. At present, the world's precision casting process is developing rapidly and widely.From the current situation, the future development trend of this process is that the casting products are getting closer and closer to the parts, and the traditional precision casting is only as a blank, which has not adapted to the market's rapid response.The complexity of the components and quality level is higher and higher, development means more and more strong, professional collaboration began to emerge, and the application of CAD, CAM, CAE, become the main components of product development technology.
H4. From the analysis of current development situation, the application surface of investment precision casting technology is very broad, and its future development prospect is quite broad.
