30ppi Casting Filter is widely used in the filtration and purification of various aluminum and aluminum alloy melts such as continuous casting, semi-continuous casting, gravity casting casting, and low-pressure casting casting.

The alumina ceramic foam filter product effectively eliminates the solid inclusions in the molten metal, so the aluminum alloy can be successfully forged, aluminum foil manufacturing, extrusion processing and other processes to obtain superior aluminum products. The product has a selection range of 10ppi coarse pore size to 70ppi very fine pore size, so there will always be a product standard that suits your requirements. Both ordinary sizes and special sizes required by customers can meet the requirements.

30ppi Casting Filter has a natural chemical adsorption (affinity) ability for impurities such as aluminum melt oxide.
Adsorb the impurities in the molten metal (including particles smaller than the pore size) on the inner wall of the hole to improve the filtering effect.
The advanced extrusion production process makes the ceramic filter have a unique square and triangle design, which increases the contact area with the ceramic.
Improve the ability of the filter to absorb and capture small impurities, which is better than the non-extrusion filter, and the molten metal flows smoothly.
Improved pouring speed and continuity.
Reduce casting scrap rate.
Improve the mechanical properties of castings and extend the service life.

30ppi Casting Filter

Ceramic foam filter Pore Size (PPI): 10/20/30/40/50/60

30ppi 40ppi Foundry Filter is the most commonly used ceramic foam filter in the aluminum casting industry.
Ordinary aluminum casting usually uses 10-40ppi ceramic filter plates.
Aviation and high-quality aluminum materials usually use 30-60ppi ceramic filter plates.

The foam ceramic filter product is a ceramic product made by a special process and has a foam-like porous structure.
It has many advantages such as stable chemical performance, high strength, high temperature resistance, good thermal shock resistance, and large specific surface area. It is widely used in metallurgy, casting, environmental protection and other fields.
