There is a foam ceramic filter manufacturing process for manufacturing ceramic foam filters for casting. The polymer sponge method, which will be described in more detail here, creates an open-pore structure by impregnating a polymer sponge with a ceramic slurry, and then burning it to leave the porous ceramic. Direct foaming methods can produce open-cell […]

Ceramic foam materials are very useful in filtering molten metal, especially molten aluminum. It is used to remove or reduce entrained solids from the final cast product, especially when the resulting metal is used in decorative products, such as decorative veneers or plates made of aluminum alloy. Adtech alumina ceramic foam filter has a high-temperature […]

In order to obtain the best mold filling rate, it is important to calculate the appropriate ceramic foam filters size for each specific casting application. The filter must be large enough so that it will not obstruct or block the flow of molten metal or be blocked by residual inclusions before casting is complete. In […]

The double CFF filter boxes can be operated as a single filter box, where a relatively coarse filter is used for standard products. For key products, when a finer filter is required, the filter box should be used as a double filter box to provide sufficient filtration area to avoid blockage or excessive metal height […]

It is well known that porous ceramic foam materials are particularly useful in filtering molten metals, especially aluminum alloys. The design and production of cast filters have the industry’s best inclusion reduction and flow control characteristics. The ceramic foam filter can remove the inclusions in the metal flow, reduce turbulence and ensure a quiet, smooth […]

The ceramic foam filter (CFF) molten metal filtration process depends on: alloy type, filter size, casting rate, metal temperature, etc. The grain refiner added before the filter has a particularly adverse effect on the filtration efficiency. In terms of cost and ease of use, ceramic foam filters (CFF) are generally considered to be the acceptable […]

Molten Metal Launders have a long service life. Use a new type of high-silicon melting material that is corrosion-resistant, non-sticky, and does not pollute the molten aluminum. It can meet the requirements of aluminum castings with high added value and high-tech performance. Advantages of Molten Metal Launders High strength, corrosion resistance, impact resistance, good thermal […]

Molten aluminum insulated launders are mainly used for the transportation of molten aluminum with high insulation requirements. The molten aluminum insulation launder combines the properties of organic and inorganic binders and a certain amount of new composite casting materials. These casting materials are insoluble in aluminum and can directly separate refractory and aluminum. Due to […]

The ceramic foam filter will always prevent foreign matter inclusions from entering the molten aluminum casting, and the hardness of the sample filtered by the ceramic foam filter is improved. Ceramic foam filter for molten aluminum is a convenient, cheap and effective method to reduce surface defects of castings. Features of Ceramic Foam Filter Molten […]

Aluminum foundries are using many commercially acceptable melt purification techniques to remove and separate inclusions from molten aluminum alloy before casting. These include different degassing and flux refining methods. Therefore, the quality of the molten aluminum alloy bath depends on the molten metal purification process. It is known that molten aluminum and aluminum-based alloys absorb […]
