Investment Casting Refers to the fusible material made of fusible model, on which a number of layers coated with a special fire-resistant coating, after drying and hardening to form an integral shell, and then steam or hot water from the shell Melting the mold, and then the shell placed in the sand box, surrounded by dry sand in its shape, and finally the mold into the roaster after high-temperature roasting, casting or shell by firing, in which the molten metal casting To obtain castings.
Investment Casting Precision, complex, close to the final shape of the part, can be used directly or with little processing, is a near-net shape of the advanced technology, casting industry is an excellent technology, its Application is very extensive. It is not only suitable for the casting of various types and alloys, but also has the advantages of high dimensional precision, surface quality higher than other casting methods, and even other casting methods are difficult to cast, complex, high temperature, Can be used for investment casting precision casting.
At present, the world's investment casting process is developing rapidly, widely used, from the current situation, the future development trend of the process is more and more close to casting products, parts and components, the traditional casting as a rough, The rapid response of the market. CAD, CAM, CAE become the main technology of the product development of parts and components, the complexity and quality of parts and components are getting higher and higher, and the means of R & D are getting stronger and stronger, and the professional cooperation begins to appear.
From the analysis of the current development, investment casting technology is very broad application prospects, the future development of its broad prospects.
