Ceramic Foam Filters (CFF) for metal filtration have been used commercially in the foundry industry for more than forty years, are used to produce high-quality aluminum castings for applications such as the aerospace industry. In recent years, for the non-ferrous metal industry, ceramic foam filters for metal filtration have become more and more important in […]

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 […]

Alumina ceramic foam filters for casting can be made by specific procedures and have peculiar bone-frame holes just like the shape of foam (three-dimensional connected channel) and myriad eyelets which only been found in the big-time microscope. A process for preparing a ceramic foam filter for filtering molten metal which comprises: providing a reticulated, organic […]

According to the molten Al filtration method, the molten Al is passed through a refractory ceramic foam filter to remove inclusions. Larger inclusion particles can be removed from the molten Al. However, it is difficult to remove small inclusion particles of 100 μm or smaller that account for most of the inclusions. In particular, it […]

The molten metal filtration system is still an area of concern. Relative to some applications, some existing systems have various advantages and disadvantages. Therefore, there is still a need to make further contributions in this technical field. Casting processes (such as investment casting and other casting processes) produce parts by pouring a liquid (usually metal) […]

Investment casting is the process of forming metal or metal alloy products (also called castings) by solidifying molten metal. Precision casting is an important method for producing high-quality precision casting metal products in various industries. Castings usually contain unwanted materials called “inclusions.” The generation of inclusions can be attributed to the slag or scum material […]

AdTech provides a high-efficiency ceramic foam material for filtering molten metal, especially molten aluminum. The ceramic foam material is characterized by having a three-dimensional network structure with a plurality of interconnected voids surrounded by the net of the ceramic material with ceramic fibers. The air permeability of the filter is 400 to 8000×10 -7 cm […]

Ceramic foam filter is a particularly useful filter in the filtration of molten metal. Ceramic foam filter manufacturing process is simple, immers the polyurethane foam in the ceramic slurry, and fires the polyurethane foam. It can make porous, hard, self-sustaining ceramic foam filter products. Ceramic Foam Filter Manufacturing Process The flexible foam material is impregnated […]

Asian foundry filter agent has been authorized by China’s manufacturers to sell foam ceramic filters to local aluminum plants. The purification purpose of ceramic foam filter in aluminum foundry is to remove alumina slag and hydrogen from aluminum melt to improve the process and mechanical properties of aluminum materials or products. In the process of […]

The quality of aluminum melt is very important, and it greatly affects the subsequent processing performance and the quality of the final product. Therefore, all countries in the world wish the purification of aluminum melt very seriously. Ceramic foam filtering technology has been used to remove inclusions in molten aluminum for more than 30 years. […]
