What are the advantages of cast iron parts compared to other parts?

1. Iron castings are affordable, repeatable, and have the characteristics of forging.

2. The surface finish of iron castings is high.

3. The sand core and core making part are eliminated, eliminating casting defects and scraps caused by core making and core laying.

4. No box and no mold, which simplifies the modeling process and eliminates casting defects and scraps caused by taking molds and boxes.

5. Modeling with dry sand without the use of binders, water and additives eliminates casting defects and scraps caused by water, additives and binders.

6. The sand processing system is simplified, the sand can be reused, and the sand making department and the waste sand disposal department are omitted.

7. It is convenient for sand falling and reduces the workload and labor intensity of sand falling.

8. No burrs on iron castings, reducing cleaning and grinding workload by more than 50%.

9. Iron casting manufacturers can set gates with reasonable shapes at ideal positions, which are not restrained by traditional factors such as analysis and mold taking, and reduce internal defects in iron castings.

10. Negative pressure pouring is conducive to the filling and shrinking of molten metal and improves the density of cast iron.
