Casting is one of the most widely used industries for foam ceramic filters. Its function is to make the turbulent and tumbling molten metal become smooth, uniform and clean after passing through the honeycomb hole of the foam ceramic, thereby greatly reducing the casting rejection rate caused by casting defects such as non-metallic inclusions and saving production costs.

Excellent raw materials and advanced production technology ensure that the filter has a stable dimensional tolerance, and at the same time meet the requirements of manual modeling and more efficient mechanized production lines, and ensure that the product quality of the foundry meets the international quality standards. Alumina foam ceramic filter, suitable for temperature 1250℃, suitable for filtration and purification of aluminum and alloy solutions. In order to meet the increasing quality requirements of aluminum castings, the use of alumina foam ceramic filters (plates) is becoming more and more important. Filters are also widely used in ordinary sand casting such as wet mold casting and permanent mold casting such as automobile aluminum parts casting.
