Development prospects of precision casting

Investment 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 an integral shell, and then steam or hot water is used from the shell Melt the model, then put the mold shell in the sand box, fill with dry sand modeling around it, and finally put the mold into the roasting furnace for high temperature roasting. After the mold or shell is roasted, the molten metal is poured into it. Get castings.

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 processing or with little processing. It is an advanced technology with near net shape and an excellent process technology in the foundry industry. The application is very wide. 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 difficult-to-process castings that are difficult to cast by other casting methods. Can be cast by investment casting.

At present, the world's investment precision casting forming technology is developing rapidly and widely used. From the current situation, the future development trend of this technology is that casting products are getting closer and closer to parts and components. Traditional precision castings are only used as blanks and are no longer suitable. The rapid response of the market. The complexity and quality of parts products are getting higher and higher, research and development methods are getting stronger and stronger, professional collaboration is beginning to emerge, and the application of CAD, CAM, and CAE has become the main technology for parts product development.

From the analysis of the current development situation, the application of investment casting technology is very wide, and its development prospects in the future are expected to be broad.
