The final molten aluminum filtration step is usually a ceramic foam filter (CFF). This is a single-use disposable filter made of hard porous ceramic foam with strictly controlled pore size. Due to their simple operation and short-term good results, these are usually the only filtration equipment in many foundries. The three key parameters of CFF […]

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 molten Al ceramic foam filter plate supplied by our company can effectively remove various inclusions in the molten aluminum with a fineness of micrometers, so that the aluminum water becomes a smooth laminar flow, which is conducive to filling; it has good mechanical strength and chemistry Stability, excellent aluminum water scouring resistance; strictly controlled […]

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. […]

The basic principle of impurity removal is to use the difference between the density and viscosity of the impurity and the aluminum melt to separate the impurity from the aluminum melt by adding certain elements or using physical methods. Specific methods for impurity removal include filtration, electric flux, electromagnetic purification, and flux refining methods. Filtration […]

Aluminium is melted in a melting furnace before further processing and almost always filtration is required. The ceramic foam filter filtration method depends on the casting technique used or the treatment of the molten aluminum. It is generally believed that it is possible and beneficial only when sufficient amounts of metal are used. However, filters […]

Aluminum casting filter is composed of a porous body, having two end surfaces, an outer peripheral surface, and partition walls, forming a plurality of main passages of purified fluid. It from one end surface to the other end surface, and arranged in the filter membrane, formed on the inner wall surface of the main flow […]

The Zirconia Ceramic Foam Filter can make the molten metal fill the cavity more evenly. The molten metal has a higher tendency to turbulence during pouring. The turbulent flow through the three-dimensional pore structure of the zirconia foam ceramic filter is finally converted into a very stable layer flow. Laminar flow has a better filling […]

Foundry ceramic filters are porous refractory components designed to remove non-metallic inclusions, oxide films, and entrained slag from molten metal during casting. A properly specified ceramic filter reduces inclusion content by 50–90%, directly cutting scrap rates, improving mechanical properties, and extending die and tool life downstream. If you’re seeing porosity defects, surface cracks, or parts […]

AdTech produces non-stick foam CFF filter to improve the quality of aluminum and aluminum alloy castings. The use of aluminum alloy castings is increasing, and the requirements for castings are becoming higher and higher. In addition to ensuring chemical composition, mechanical properties and dimensional accuracy, aluminum alloy castings are not allowed to have casting defects […]
