1、FCF-T SiliconCarbideCeramicFoam FilterSIC ceramic foam filter is specially for gray and ductile iron casting filtration,also it can be used for non-ferrous application.The filter's open pore structure was specially developed for the filtration of cast iron and prevents the ingress of slag, metal

2、 reaction products, inoculant residues or sand grains into the mold cavity. The inherently large surface area is well suited to intensive filtration and even finely distributed slag particles are retained both on the filter surface and in the filter structure.Such high filtration effectiveness, comb

The filters can be positioned vertically, horizontally, or diagonally in a suitably designed runner system.Whyuseceramicfoam filters-Simplifygatingsystemandincrease yield.-Reducedimpurities
