The Ceramic Foam Filter PPI refers to the plastic material used to make the ceramic foam and is found from the average number of pore boundaries encountered per inch. More recently the CFFs are graded into different PPI categories according to air permeability. The type of filtration occurring in a CFF can be divided into […]

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 […]

These ceramic foam filters for foundries are designed for molten metal casting. Ceramic foam filters have good thermal properties and mechanical properties for high-temperature environments. Currently, in the molten and casting process of various metals, the rate of casting waste is usually reached 60 ~ 80% due to non-metallic impurities and pores defects. Casting defects […]

The foam ceramic filters for foundries are single-use disposable filters, made of porous ceramic foam, and has a strictly controlled pore size. Due to their simple operation and short-term good results, these are usually the only filtration equipment in many foundries. It is not enough that the foam ceramic filter has good filtration efficiency. It […]

Alumina ceramic foam filters are specially developed by AdTech for molten Alu filtration. The molten aluminum flows through the tortuous and porous three-dimensional foam structure, and the tiny impurities are trapped, adsorbed, deposited, and firmly adhered to the pore walls, filtering out the micron-level impurities in the molten aluminum, and solving the aluminum alloy’s sensitivity […]

Alumina ceramic foam filters for casting are widely used in the production of aluminum profiles, aluminum foil, and aluminum alloys. The size is available in square, and custom geometric shapes; sizes ranging from 10mm up to 600mm, and thicknesses from 10-50mm. The most common porosities are 10ppi, 20ppi, 30ppi, 40ppi, 50ppi, 60ppi. 1.10-30ppi continuous casting […]

Ceramic foam filters foundry are just developed as new type of molten metal filters to decrease casting flaw in recent years, play a vital role in the metal casting and foundry industries, where they are used to filter out impurities in molten metal to improve the quality and performance of the end product. Even the […]

AdTech improves a ceramic foam filter for molten metal filtration, especially aluminum-based alloys. It is an objective to provide a ceramic foam filter characterized by the cost of raw materials. Ceramic foam filters are produced by impregnating polyurethane foam with a ceramic slurry, drying, baking and finally firing the foam in the oven. Metal casting […]

The alumina ceramic foam filter is widely used in aluminum foundry. It has good high-temperature performance, and can filter aluminum metal liquid without polluting the alloy, and has a good through porosity, so it has good filtration and adsorption. The capacity of oxide inclusions and flux inclusions in the metal solution is obtained. It has […]

The alumina ceramic foam filter for casting can capture the inclusions according to a certain mechanism, thereby purifying the metal. In 1978, the United States developed a new filter-ceramic foam filter, which provides a high-efficiency filter for the production of aluminum castings, and is widely used in the production of semi-continuous ingots and molded castings.
