What are the advantages of lost foam casting
Advantages of lost foam casting：
1.The size and shape of castings are good repeatability and have the characteristics of precision casting.
1.The size and shape of castings are good repeatability and have the characteristics of precision casting.
2. High surface finish of castings.
3. The casting defects and waste products caused by the sand core and the core-making department have been cancelled.
4. Without closing the box and not taking the mold, the molding process is greatly simplified and the casting defects and waste products caused by taking the mold and closing the box are eliminated.
5. By using dry sand molding without binder, moisture and additive, all kinds of casting defects and waste products caused by moisture, additives and binders are eliminated.
6. The sand treatment system is greatly simplified, the molded sand can all be reused, and the molding sand preparation department and waste sand treatment department are cancelled.
7. Sanding is extremely easy, which greatly reduces the workload and labor intensity of sanding.
8. There is no flying edge burr in the casting, which reduces the work of cleaning and grinding by more than 50%.
9. The reasonable shape of the gate and riser can be set in the ideal position, which is not restricted by the traditional factors such as parting, mold taking and so on, and the internal defects of the casting are reduced.
10. Negative pressure casting is more conducive to mold filling and shrinkage of liquid metal, and improves the microstructure density of castings.
11. Combined casting, more than one box, which greatly improves the process yield and production efficiency of castings.
12. The machining margin and machining cost are reduced.
13. It is easy to realize mechanized automatic assembly line production, the production line is flexible, and the castings of different alloys, shapes and sizes can be produced in one production line.
14. Draft angle can be cancelled.
15. The service life of the metal mold can reach more than 100,000 times, which reduces the maintenance cost of the die.
16. Reducing dust, smoke and noise pollution, greatly reducing the working environment of foundry workers and reducing labor.
Dynamic intensity, an industry dominated by male workers can become an industry dominated by female workers.
17. The process operation is simplified, and the technical proficiency requirements of workers are greatly reduced.
18. The shape of the parts is not limited by the traditional casting technology, which liberates the mechanical designers so that they can freely design the ideal casting shape according to the performance of the parts.
19. It can reduce the weight of castings.
20. Reduced production cost.
21. The factory design is simplified, the fixed asset investment can be reduced by 30% to 40%, and the floor area and building area can be reduced.
Reduce 30% to 50%, and reduce power consumption by 10% to 20%.
22. Lost foam casting process is widely used, not only for cast steel and cast iron, but also for cast copper, cast aluminum and so on.
23. The lost foam casting process is not only suitable for castings with simple geometry, but also suitable for castings with multi-open edges, multi-cores and complex geometry, which are difficult to be cast.
24. The lost foam casting process can realize pouring under microtremor, promote the formation of metallographic structure with special requirements, and help to improve the internal quality of castings.
25. Combined casting in dry sand can remove sand easily and synchronize the temperature, so the waste heat can be used for heat treatment.
In particular, the water edge treatment of high manganese steel castings and the solid solution treatment of heat resistant steel castings have a very ideal effect, which can save a lot of energy and shorten the processing cycle.
26. By using the lost foam casting process, castings of any size can be completed according to the melting ability.
