Development prospect of precision casting

Revestment precision casting is refers to the use of fusible materials meltability model, on which the coated with several layers of special refractory coating, after drying and hardening type to form a whole shell, reoccupy steam or hot water from the melt in the shell model, and then put type shells in the sand, dry sand by filling in all round its modelling, finally will be cast into the furnace after high temperature roasting, cast type or shell after roasting, A casting is produced by pouring molten metal into it.

Investment precision casting products are precise, complex, close to the final shape of parts, can be directly used without processing or little processing, is a nearly net form of advanced technology, is an excellent technology in the casting industry, its 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. Even the complicated, high-temperature resistant and difficult to process castings that are difficult to be cast by other casting methods can be cast by investment precision casting.

At present, the investment precision casting process in the world develops rapidly and is widely used. From the current situation, the future development trend of this process is that the casting products are more and more close to the parts products, while the traditional investment casting is only as blank, which has not adapted to the rapid strain of the market. The complexity and quality of parts and components products are getting higher and higher, the research and development means are getting stronger and stronger, and the professional cooperation has begun to appear. The application of CAD, CAM and CAE has become the main technology of parts and components product development.

From the analysis of the current development situation, the application of investment precision casting technology is very wide, and its future development prospect should be broad.
