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 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 […]
