(Summary description)Investment casting refers to the use of fusible materials to make a fusible model, which is coated with several layers of special refractory paint, after drying and hardening to form an integral mold shell, then steam or hot water is used to remove the mold shell Melt the model, then put the mold shell in the sand box, fill it with dry sand molding, and finally put the mold into a roaster for high temperature roasting. After the mold or shell is roasted, pour molten metal into it Get the casting.

Investment casting refers to the use of fusible materials to make a fusible model, which is coated with several layers of special refractory paint, after drying and hardening to form an integral mold shell, then steam or hot water is used to remove the mold shell Melt the model, then put the mold shell in the sand box, fill it with dry sand molding, and finally put the mold into a roaster for high temperature roasting. After the mold or shell is roasted, pour molten metal into it Get the casting.

The products obtained by investment precision casting are precise and complex, close to the final shape of the part, and can be used directly without or with little processing. It is an advanced process with near net shape forming and an excellent process technology in the casting industry. It is widely used. 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. Even casting methods that are difficult to cast are complex, high temperature resistant, and not easy to process castings. Can be cast by investment casting.

At present, the investment casting process in the world is developing rapidly and widely used. From the current situation, the future development trend of the process is that the casting products are getting closer and closer to the parts products. The traditional precision castings are only used as blanks, which is no longer suitable. Rapid market response. The complexity and quality of parts and components are getting higher and higher, and R&D methods are getting stronger and stronger. Specialized collaboration is beginning to emerge. The application of CAD, CAM and CAE has become the main technology for the development of parts and products.

Analysis from the current development situation, the application of investment precision casting technology is very extensive, and its future development prospects should be broad.
