Main advantages of lost wax castings
1. The castings are accurate in size, high in repetition accuracy, and accurate in casting.
2. The castings have a high surface finish;
3. Eliminate the core and core manufacturing department, eliminate core manufacturing and reduce casting defects and waste caused by the core;
4. Not suitable for the box, without mold, greatly simplifies the molding process, eliminates casting defects and waste caused by mold removal and boxing;
5. Dry sand molding, no adhesive, no moisture, no additives, can eliminate various casting defects and waste caused by moisture, additives and adhesives;
6. The sand processing system is greatly simplified, the molding sand can be fully reused, eliminating the molding sand preparation department and waste sand Processing department;
7. Sand dropping is extremely easy, greatly reducing the workload and labor intensity of sand dropping;
8. The casting has no burrs, which reduces the cleaning and polishing work by more than 50%;
9. The reasonable shape of the riser can be set in an ideal position, without being restricted by traditional factors such as separation and removal, and reducing the internal defects of the casting;
10. Negative pressure casting is more conducive to the filling and filling of liquid metal, thereby improving the organizational density of the casting;
11. Combined casting, multiple pieces in one box, greatly improves the process yield and production efficiency of castings;
12. Reduce processing allowance and reduce processing costs;
13. It is easy to realize mechanized automatic assembly line production. The production line has great flexibility and can realize the production of castings of different alloys, shapes and sizes on one production line;
14. The draft angle can be removed;
15. The service life of the metal mold used can reach more than 100,000 times, reducing the maintenance cost of the mold;
16. Reduce dust, smoke and noise pollution, greatly improve the working environment of foundry workers, and reduce labor
17. Simplify process operations and greatly reduce workers' Technical proficiency;
18. The shape of the parts is not restricted by the traditional casting process, so that mechanical designers can freely design the best casting shape according to the performance of the parts;
19. The weight of the casting can be reduced;
20. Reduce production costs;
21. Simplify the factory design, the fixed asset investment can be reduced by 30∽40%, the floor area and building area can be reduced by 30∽50%, and the power consumption can be reduced by 10∽20%;
22. The lost foam casting process is widely used, not only for casting steel and cast iron, but also for casting copper, casting aluminum, etc.
23. The lost foam casting process is not only suitable for castings with simple geometric shapes, but also for castings with multiple opening edges, multiple cores and complex geometric shapes, which are difficult to process with ordinary castings;
24. The lost foam casting process can realize casting under micro-impact state, promote the formation of special requirements of metallographic structure, and help improve the intrinsic quality of castings;
25. Combined with casting in dry sand, sand removal is easy and temperature is synchronized, so waste heat can be used for heat treatment. Especially the water jet treatment of high manganese steel castings and the solution treatment of heat-resistant steel castings are very effective, which can save a lot of energy and shorten the processing cycle;
26. Using the lost foam casting process, castings of any size can be completed according to the melting capacity.
27. Lost foam casting is suitable for assembly casting, and dry sand is easy to remove sand. In some materials, castings can also be used for residual heat treatment according to the application.
