Manufacturer of casting molding machine tells you how to choose a filter

Ductile iron castings are widely used in automotive, machinery, aerospace and other fields due to their excellent properties. Zoomzu casting molding machine is widely used in sand casting of ductile iron castings. In the process of casting, inadvertent process operation will cause excessive impurities in the casting and affect the surface quality. To this end, the industry has generally adopted filters to filter the molten metal, which provides a strong guarantee for the quality of ductile iron castings. So what is the choice and impact of the filter?

1. Turbulent damage to the surface quality of castings during the manufacture of ductile iron castings

In casting production, when liquid metal is injected into the cavity from the holding furnace, any turbulence will result in a thin scale on the surface of the ductile iron casting. This is an unrepairable defect that not only reduces the surface quality of ductile iron parts, but also does not allow for pressure testing due to the gap between the two walls.

2. Filtering residue in the molding process of ductile iron castings using filters

It is important to know that turbulence occurs largely because of the presence of impurities, so to avoid the formation of scale, it is necessary to prevent turbulence, and in the final analysis is to remove impurities in the metal solution. The use of the filter plays a role in this aspect. It can filter out the residue formed in each process environment, and the metal solution is poured with high purity to obtain high quality ductile iron castings.

3. Foam filter reduces impurities in ductile iron and saves sand

In the casting process, the foam filter not only reduces the amount of non-metallic inclusions in ductile iron castings, but also significantly saves sand. In this way, not only the quality of the ductile iron castings is improved, but also the amount of casting cleaning is reduced.
