Ceramic Foam Filter
Product Description
Ceramic foam filters are a new type of molten metal filter for filtering impurities from liquid metals to decrease casting flaws. They have the characteristics of lightweight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance, and high-temperature stability in molten metal.
Non-metallic inclusions in casting are one of the most main reasons for casting defects. Ceramic foam filters have a three-dimensional net structure, they can increase the surface areas and absorb the sinter, the liquid metal becomes purer, quality problems such as sand pores and air pores are much less, and the casting quality becomes much better.
Ceramic foam filters are not only widely applied in the plant of metal casting such as the casting of steel, iron, copper, and aluminum, but also be applied in gas treatment in high temperatures, carriers of catalyzers, solid heat exchange, and advanced filling for chemical industry.
We have developed a series of ceramic foam filters that are made of different materials such as alumina, silicon carbide, zirconia, and magnesia. All of the materials are available in square, round, and custom geometric shapes; Sizes ranging from 10mm up to 600mm; And thicknesses from 10-50mm. Pore densities from 10-60 PPI (pores per inch) are available.

We are a professional supplier of foundry filters in China, ceramic foam filters are the most effective filtering system available and have a unique three-dimensional channel structure. Our filtration systems can help customers remove inclusions, reduce turbulence, and provide rapid and consistent flow to improve casting quality and reduce defective rates and casting costs. They are widely used for aluminum, copper, iron, and steel casting applications.
Our ceramic foam filters have the characteristics of lightweight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance, and high-temperature stability in molten metal. It not only can filter residuum but also can adsorption, especially for tiny impurities of 1-10μm.
Our ceramic foam filter is not only applied for molten metal filtering in high temperatures But also be used for purification of high-temperature gas dust, sound insulation, biological enzyme carrier in medical preparation, catalyst carrier substrate, solid heat exchange, and advanced filling for the chemical industry.
Packaging & Shipping
Inside packing: Filters are put in small boxes and Layered packaging. There is cardboard between each layer.
Outside packing: Cartons & Pallets. Three-layer corrugated cartons and export special pallets.
The mark on cartons can be designed according to the customer's request.
