1. The casting size and shape are precise, with good repeatability and the characteristics of precision casting
2. The surface smoothness of the castings is high;
3. The sand core and core making departments have been cancelled, eliminating casting defects and waste caused by core making and cutting
4. Non conformity and non removal of molds greatly simplify the molding process, eliminating casting defects and waste caused by mold removal and closure
5. Adopting dry sand molding without binder, moisture, or any additives, various casting defects and waste caused by moisture, additives, and binders have been eradicated;
6. The sand processing system has been greatly simplified, and all molding sand can be reused, eliminating the need for molding sand preparation and waste sand treatment departments;
7. Sand falling is extremely easy, greatly reducing the workload and labor intensity of sand falling;
8. The castings have no burrs or flying edges, reducing the cleaning and polishing workload by more than 50%;
9. Reasonable shaped sprues can be set at ideal positions, without being restricted by traditional factors such as parting and mold taking, reducing internal defects in castings;
10. Negative pressure casting is more conducive to the filling and shrinkage of liquid metal, and improves the density of the casting structure;
11. Combination casting, with multiple pieces in one box, greatly improves the process yield and production efficiency of castings;
12. Reduced processing allowance and lowered machining costs;
13. Easy to implement mechanized automatic assembly line production, with high production line flexibility, capable of producing different alloys, shapes, and sizes of castings on one production line;
14. The draft angle can be cancelled;
The lifespan of the metal molds used can reach over 100000 times, reducing the maintenance costs of the molds;
16. Reduced dust, smoke, and noise pollution, greatly improved the working environment for foundry workers, reduced labor intensity, and transformed industries dominated by male workers into industries dominated by female workers;
17. Simplified the process operation and greatly reduced the requirement for workers'' technical proficiency;
The shape of the parts is not limited by traditional casting processes, freeing mechanical designers to freely design the most ideal casting shape based on the performance of the parts;
19. Can reduce the weight of castings;
20. Reduced production costs;
21. The factory design is simplified, fixed assets investment can be reduced by 30-40%, floor area and building area can be reduced by 30-50%, and power consumption can be reduced by 10-20%;
22. The lost foam casting process is widely used, not only for cast steel and iron, but also for casting copper, cast aluminum, etc;
23. The lost foam casting process is not only suitable for castings with simple geometric shapes, but also for castings with multiple edges, multiple cores, and complex geometric shapes that are difficult to handle in ordinary casting;
24. The lost foam casting process can achieve casting under microseismic conditions, promote the formation of metallographic structures with special requirements, and improve the intrinsic quality of castings;
25. Combining casting in dry sand makes sand removal easy and temperature synchronized, so residual heat can be used for heat treatment. Especially for the water cutting treatment of high manganese steel castings and the solid solution treatment of heat-resistant cast steel parts, the effect is very ideal, which can save a lot of energy and shorten the processing cycle;
Using the lost foam casting process, castings of any size can be completed based on their melting capacity.
