Investment precision casting refers to the use of fusible materials to make a fusible model, which is coated with several layers of special refractory coatings, which are dried and hardened to form a monolithic shell, and then steam or hot water is used from the shell. Melt off the model, then place the mold case in a sand box, fill it with dry sand, and finally place the mold in a baking furnace for high temperature baking. After the mold or mold case is fired, cast molten metal into it. Get castings.
The product obtained by investment precision casting is precise and complex, which is close to the final shape of the part. It can be used directly without machining or with little processing. It is an advanced process with near net shape. It is an excellent process technology in the casting industry. The application is very extensive. It is not only suitable for the casting of various types and alloys, but also produces castings with higher dimensional accuracy and surface quality than other casting methods, and even other casting methods that are difficult to cast, complex, high temperature resistant, and difficult to process. Both can be made by investment precision casting.
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 this process is that casting products are getting closer to parts products. Traditional precision castings are only used as rough stocks, and they are no longer suitable. Rapid market response. The complexity and quality of component products are getting higher and higher, research and development methods are getting stronger, professional collaboration is beginning to emerge, and the application of CAD, CAM, CAE has become the main technology for component product development.
From the analysis of the current development situation, the application of investment precision casting technology is very extensive, and its development prospects are expected to be broad in the future.
