The advantages of lost mold casting
Main advantages of vanishing die casting
1. Precise casting size, high repetition accuracy and precise casting.
2. High surface finish of casting;
3. Eliminate core and core manufacturing departments, eliminate core manufacturing and reduce casting defects and wastes caused by core;
4. It is not suitable for box body and no mold, which greatly simplifies the molding process and eliminates casting defects and wastes caused by mold removal and packing;
5. Dry sand molding, no adhesive, no moisture, no additives, can eliminate all kinds of casting defects and wastes caused by moisture, additives and adhesives;
6. The sand treatment system is greatly simplified, molding sand can be completely reused, eliminating molding sand preparation department and waste sand treatment department;
7. Sand falling is extremely easy, greatly reducing the workload and labor intensity of sand falling;
8. No burr on casting, reducing cleaning and polishing by more than 50%;
9. The proper shape of the riser can be set in an ideal position, independent of traditional factors, such as separation and removal, and reduce internal defects of the casting;
10. Negative pressure casting is more conducive to the filling and filling of liquid metal, thus improving the microstructure density of the casting;
11. Combined casting, more than one box, greatly improving the casting process yield and production efficiency;
12. Reduce processing allowance and processing cost;
13. It is easy to realize automatic automatic production line, and the production line has great elasticity, which can realize the production of casting of different alloy, shape and size in one production line;
14. The mold drawing Angle can be removed;
15. The service life of the metal mold can reach more than 100,000 times, which reduces the maintenance cost of the mold;
16. Reduce dust, smoke and noise pollution, greatly improve the working environment of the foundry workers, reduce the labor forceDynamic strength: industries dominated by male workers can become industries dominated by female workers;
17. Simplify the process operation and greatly reduce the technical proficiency of workers;
18. The shape of 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 parts;
19. Can reduce the weight of casting;
20. Reduce production costs;
21. Simplify plant design, reduce investment in fixed assets by 30 to 40%, land area and building area by 30 to 50%, and power consumption by 10 to 20%;
22.Lost mold casting process is widely used, not only for casting steel, cast iron, but also for casting copper, aluminum and so on.
23. Epc process is not only applicable to castings with simple geometry, but also to castings with multiple open edges, multiple cores and complex geometry, which are difficult to be processed with ordinary castings;
24. Epc process can realize casting under micro-impact state, promote the formation of special requirements of metallographic structure, and help to improve the inherent quality of casting;
25. Combined with casting in dry sand, sand removal is easy and temperature synchronized, so waste heat can be used for heat treatment.Especially the water knife treatment of high manganese steel castings and the solid solution treatment of heat resistant steel castings are very effective, which can save a lot of energy and shorten the processing cycle.
26. With epc process, castings of any size can be made according to melting capacity.
27.Lost mold casting is applicable to group casting, dry sand is easy to remove sand.In some materials, castings may also be used for residual heat treatment according to application.
