The Development Prospect Of Precision Casting
Oct 03, 2023| Investment precision casting refers to the use of fusible materials to make a fusible model, on which a number of layers of special refractory paint are coated, after drying and hardening to form an integral shell, and then the model is melted from the shell with steam or hot water, and then the shell is placed in the sand box, filled with dry sand around it, and finally the mold is put into the roasting furnace after high temperature roasting, and the casting or shell is roasted, and the molten metal is poured into it to obtain the casting.
The products obtained by investment precision casting are precise, complex, close to the final shape of the parts, and can be used directly without processing or with little processing, which is an advanced process that is close to net forming, and is an excellent process technology in the foundry industry, which 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, and even complex, high-temperature resistant and not easy to process castings that are difficult to be cast by other casting methods.
At present, the world's investment precision casting forming process 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 and components products, and the traditional precision castings are only used as blanks, which have not adapted to the rapid adaptation 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, professional cooperation has begun to appear, and the application of CAD, CAM and CAE has become the main technology for the development of parts and components.
From the analysis of the current development situation, the application of investment precision casting technology is very extensive, and its development prospects in the future are broad.
