Lost Wax Casting is a fusible model made of fusible material, coated with several layers of special refractory coating, dried and hardened to form a monolithic shell, and then steam or hot water from the shell. The model is melted, and then the shell is placed in a sand box, and the dry sand shape is filled around it. Finally, the mold is placed in a roaster and subjected to high-temperature roasting, and the mold or shell is fired, and molten metal is poured therein. Get castings.
The products obtained by Lost Wax Casting are precise and complex, close to the final shape of the part, and can be used directly without machining or processing. It is an advanced process of near-net shape formation and an excellent process technology in the foundry industry. The application is very extensive. It is not only suitable for the casting of various types and various alloys, but also produces castings with higher dimensional accuracy and surface quality than other casting methods, and even castings that are difficult to cast by other casting methods, which are difficult to mold, are not easy to process. Can be cast by Lost Wax Casting.
At present, the world's Lost Wax Casting precision casting process is developing rapidly and widely used. From the current situation, the Copper Alloy Casting future development trend of the process is that the casting products are getting closer to the parts and components, and the traditional precision castings are only used as blanks. The rapid response 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, and professional collaboration is beginning to appear. The application of CAD, CAM and CAE has become the main technology for component product development.
From the current development analysis, the application ofLost Wax Casting precision casting technology is very extensive, and its development prospects are broad in the future.
