Casting Filter for Molten Aluminum | Ceramic Foam Filters

Metal casting is one of the most widely used industries in the foam ceramic filter. The function of the Casting Filter is to make the turbulent metal liquid become stable, uniform, and clean after passing through the honeycomb holes of the foam ceramic. This greatly reduces the scrap rate of castings (caused by molten aluminum inclusions), thereby saving production costs. Ceramic foam filters are mainly used for filtering aluminum and alloys in foundries and foundries.

The Casting Filter has excellent resistance to corrosion and corrosion of molten aluminum, can effectively remove inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metals can produce higher quality castings, fewer scraps, and fewer inclusion defects, all of which help increase profits.

Casting Filter

When the molten metal is blocked in the mold, the inclusions will automatically separate. After the treatment, the remaining impurities are larger than the filtered three-dimensional connecting channel and will be removed by surface filtration.

The internal filtering function can remove smaller impurities. The porosity of the ceramic foam filter for casting is very high, which can calm the turbulence of the metal, especially the bone frame structure can make it stable. The vortex can generate bubbles and take away some impurities. Our products can prevent swirling.

Ceramic foam filter for casting is a phosphate-free, high alumina product, which is characterized by high porosity and mechanochemical stability, and has excellent heat resistance and corrosion resistance to molten aluminum.

When filtering molten aluminum, it can effectively remove inclusions, reduce trapped gas and provide laminar flow. It is the first choice for the filtration of molten non-ferrous metals.

Ceramic foam filters are widely used for molten aluminum filtration in primary and secondary aluminum foundries. They are also used as filter media in gas-liquid and liquid-solid separation projects.

The ceramic foam filter is equipped with soft/hard gaskets to prevent metal bypass. Its pore size is 20-60ppi. Special sizes can also be ordered.
