Revestment precision casting is refers to the use of fusible materials meltability model, on which the coated with several layers of special refractory coating, after drying and hardening type to form a whole shell, reoccupy steam or hot water from the melt in the shell model, and then put type shells in the sand, dry sand by filling in all round its modelling, finally will be cast into the furnace after high temperature roasting, cast type or shell after roasting, and are casting in pouring molten metal.
Investment precision casting products precision, complex, close to the final shape of parts, can not be processed or rarely processed directly used, is a near net shape of the advanced technology, 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 produces castings with higher dimensional accuracy and surface quality than other casting methods, and even complex, high-temperature resistant and non-easy to process castings that are difficult to be cast by other casting methods.
At present, the world's investment precision casting process has developed rapidly and been widely used. From the current situation, the future development trend of this process is that the casting products will be more and more similar to the parts and components, and the traditional investment casting products will only be used as blank, which cannot adapt to the rapid strain of the market. The degree of complexity and quality of component products are getting higher and higher, the means of research and development are getting stronger and stronger, and professional cooperation begins to emerge. The application of CAD, CAM and CAE has become the main technology of component product development.
From the analysis of the current development situation, the application of investment casting technology is very broad, and its future development prospects want to be broad.
