What are the advantages of cast iron parts over other parts?

1. Good repeatability, with the characteristics of casting;

2. The surface finish of cast iron parts is high;
3. The sand core and core making department have been canceled, and the casting defects and waste products caused by core making and lower core have been eliminated;
4. Not in the box, not taking the mold, simplifying the modeling process, the casting defects and waste products caused by taking the mold, the box;
5. The use of dry sand molding without binder, moisture, and without any additives, various casting defects and waste products caused by moisture, additives and binders;
6. Simplify the sand treatment system, the sand can be fully reused, and cancel the sand preparation department and the waste sand treatment department;
7. Easy sand fall, reduce the workload and labor intensity of sand fall;
8. Iron castings have no flash burrs, which reduces the cleaning and polishing workload by more than 50%;
9. A reasonable shape of the sprue can be set in the ideal position, which is not restricted by traditional factors such as parting and mold taking, and reduces the internal defects of cast iron parts;
10. Negative pressure pouring is beneficial to filling and feeding of liquid metal and improves the tissue density of cast iron;
11. Combination pouring, a box of multiple pieces, improve the process of cast iron production rate and production efficiency;
12. Reduce the processing margin, reduce the cost of machining;
13. It is easy to realize mechanized automatic assembly line production, the production line is flexible, and the production of different alloys, different shapes and different sizes of cast iron parts can be realized on one production line;
14. The draft angle can be canceled;
The service life of the metal mold can reach more than 100000 times, which reduces the maintenance cost of the mold;
16. Reduce dust, smoke and noise pollution, the labor environment for foundry workers, reduce labor intensity, and industries dominated by male workers can become industries dominated by female workers;
17. Simplify the process operation and reduce the technical proficiency requirements of workers;
18. The shape of the part is not limited by the traditional casting process, which liberates the mechanical designer and makes it free to design the ideal shape of the cast iron according to the performance of the part;
19. Can reduce the weight of cast iron parts;
20. Reduced production costs;
21. Simplify the factory design, the investment in fixed assets can be reduced by 30 ∽ 40%, the floor area and construction area can be reduced by 30 ∽ 50%, and the power consumption can be reduced by 10 ∽ 20%;
22. Cast iron technology is widely used, not only for cast steel, cast iron, suitable for cast copper, cast aluminum and so on;
23. The iron casting process is not only suitable for iron castings with simple geometric shapes, but also for iron castings with multiple open edges, multiple cores and complex geometric shapes that are difficult for ordinary casting;
24. Iron casting process can achieve micro-seismic state of pouring, the formation of the required gold-phase structure, is conducive to improving the inherent quality of iron castings;
25. Combined pouring in dry sand, sand removal is easy and the temperature is synchronized, so heat treatment can be carried out using waste heat. In particular, the water edge treatment of high manganese steel castings and the solid solution treatment of heat-resistant steel castings have very satisfactory results, which can save a lot of energy and shorten the processing cycle;
26. Using the cast iron process, iron castings of any size can be completed according to the melting capacity.
