Do you know about investment casting?

Investment precision casting refers to the use of fusible raw materials to make a fusible model, and apply several layers of specially made fire-resistant coatings on it. After drying and hardening to produce an overall shell, it is then molded with steam or boiling water. Melt the model in the shell, then place the shell in the sand box, fill with dry sand around it, and finally put the mold in the calciner to undergo high-temperature sintering. After the mold or shell is sintered, Among them, molten metal materials are poured to obtain castings.

Investment casting obtainedThe products are fine and complex, close to the final appearance of the part, and can be directly applied without production or processing. It is an advanced technology with near net production and an excellent production technology in the casting field. Its application is very common. . It is not only suitable for casting of various types and alloys, but also the precision and process performance of the castings produced are higher than other casting methods, and even other casting methods are difficult to cast. Castings that are easy to produce and process can be cast by investment casting.

At this stage, the global investment precision casting molding processing technology is developing rapidly and widely used. From the current trend, the future development trend of the processing technology in the future is that the casting products are getting closer to the parts products, and the traditional precision castings are only made. It is a blank, which has long been unsuitable for the rapid response of the market. The complexity and quality level of parts products are getting higher and higher, product research and development methods are getting stronger and stronger, and systematic cooperation is beginning to appear.The application of CAD, CAM, and CAE has become a key process in the research and development of parts and components.

Analyzed from the current development status, the application of investment casting technology is very common, and its development potential is expected to be broad in the future.
