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.
The products obtained by investment casting are precise and complex, which are close to the final shape of parts and can be used directly without processing or little processing.It is not only applicable to casting of various types and various alloys, but also produces castings with higher dimensional accuracy and surface quality than other casting methods.
At present, the world's investment precision casting forming process develops rapidly and is widely used. According to the current situation, the future development trend of this process is that casting products are getting closer and closer to parts and components, and the traditional precision casting is only used as a blank, which cannot adapt to the rapid strain of the market.The complexity and quality of parts and components are getting higher and higher, the research and development methods are getting stronger and stronger, and professional collaboration is emerging. The application of CAD, CAM and CAE has become the main technology of parts and components product development.
Based on the current development, the application of investment casting technology is very extensive, and its future development prospects are very broad.Precision foundry
