The advantages of ductile iron castings compared to other castings

- Mar 14, 2021-

What are the advantages of ductile iron castings, and what are the advantages over other castings? Let me give you a detailed introduction.

  1. Good repeatability and the characteristics of precision casting;

  2. The surface finish of ductile iron parts is high;

  3. The sand core and core making department are eliminated, and the casting defects and waste products caused by core making and lowering are eliminated;

  4 .Do not fit the box and take the mold, which greatly simplifies the molding process and eliminates the casting defects and waste caused by mold taking and closing;

  5. Adopt dry sand molding without binder, moisture, and any additives. In addition to various casting defects and waste products caused by moisture, additives and binders;

  6. The sand processing system is greatly simplified, the molding sand can be all reused, and the molding sand preparation department and waste sand processing department are eliminated;

  7. Sand is easy, which greatly reduces the workload and labor intensity of falling sand;

  8. Nodular cast iron parts have no flash burrs, which reduces the cleaning and polishing workload by more than 50%;

  9. A reasonable shape of pouring riser can be set at an ideal position. Restricted by traditional factors such as parting and mold taking, the internal defects of ductile iron parts are reduced;

  10. Negative pressure pouring is conducive to the filling and feeding of liquid metal, and improves the density of ductile iron parts;

  11. Combined pouring, multiple pieces in one box, greatly improves the process yield and production efficiency of ductile iron parts;

  12. Reduces processing margin and reduces machining costs;

  13. It is easy to realize mechanized automatic assembly line production, and the production line is flexible and can be Realize the production of ductile iron parts of different alloys, different shapes and different sizes on one production line;

  14. The draft angle can be eliminated;

  15. The life of the used 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 labor environment of foundry workers, reduce labor intensity, and the industry dominated by male workers can be turned into an industry dominated by women;

  17. The process operation is simplified, and the labor The technical proficiency requirements are greatly reduced;

  18. The shape of the parts is not restricted by the traditional casting process, which liberates the mechanical design workers, so that they can freely design the ideal ductile iron shape according to the performance of the parts;

  19. Can reduce the weight of ductile iron castings;

  20. Reduce production costs;

  21. Simplify factory design, reduce investment in fixed assets by 30∽40%, reduce floor space and building area by 30∽50%, and reduce power consumption by 10∽ 20%;

  22. The process of ductile iron casting is widely used, not only for cast steel, cast iron, but also for cast copper, cast aluminum, etc.;

  23. The process for ductile iron casting is not only suitable for ductile iron parts with simple geometric shapes, but also suitable for ordinary casting Ductile iron castings with multiple open edges, multiple cores, and complex geometric shapes that are difficult to handle;

  24. Ductile iron castings can be poured in a micro-seismic state, promote the formation of metallographic structures with special requirements, and help improve the intrinsic quality of ductile irons Quality;

25. Combined pouring in dry sand, easy to screenout, temperature synchronization, so the waste heat can be used for heat treatment. Especially the water-blade treatment of high-manganese steel ductile iron castings and the solution treatment of heat-resistant steel castings are very effective, can save a lot of energy, and shorten the processing cycle;

  26. Using ductile iron castings can be based on melting capacity. Complete any size ductile iron parts.
