The use of alumina foam ceramic filters for foundry can purify molten aluminum, it has brought huge benefits to the strip foil and its products. For manufacturers of aluminum alloy profiles, there are several advantages: Improve extrusion productivity: When using foam ceramic filters to purify alloy extrusion materials, we have inspected a certain mold and […]

The filter plate has an open-pored structure, which is characterized by having a plurality of interconnected voids, so that molten metal can pass through to remove entrained solids. Such filters include solid filter plates made of sintered ceramic aggregate. A ceramic foam filter with an open-cell structure, which is characterized by a plurality of interconnected […]
The porous ceramic filter medium has a primary porous structure imparted by the foam macrostructure, which is the exoskeleton of the polyurethane precursor, and is replicated by coating with slurry, followed by drying and firing. The primary pore size is usually 3 holes per linear inch (ppi) to 100 ppi, more preferably 20 ppi to […]
The ceramic foam is made of an open-celled, preferably hydrophobic, flexible foam material having a plurality of interconnected voids surrounded by a network of said flexible foam material. Typical materials that can be used include polymer foams, such as polyurethane foams, and cellulose foams. Generally, any combustible organic plastic foam that has elasticity and the […]
