Ceramic Foam Filters from AdTech Metallurgical Materials Co., Ltd has been focusing on research, development, production, and marketing of the adhesive Alumina Ceramic Foam Filter(CFF) for aluminum alloy casting Since 2012.
The technology of AdTech Alumina Ceramic Foam Filter has been widely approved by the market and applied for producing multiple series of aluminum alloy products, such as PS baseboard for printing, canning materials, flexible packaging materials, railway vehicle, aerospace products, cables, electrical wires and other high-precision filtration and purification for casting aluminum alloy.
Filter-PAl
Ceramic Filter For Foundry is produced based on the carrier with a solid reticular structure and combined organic foam pores. The production procedure is as below, put the carrier into the thixotropic alumina slurry, adopt square to center correcting automatic extrusion process, so that the slurry evenly deposits in the foam skeleton of the carrier, after drying solidification, then the carrier will turn into the final product by roasting formed under 1180 ℃ high temperature. A ceramic Foam Filter is installed in the filter bowl for filtrating impurities in molten aluminum alloy, which helps to meet the requirement of production in high value-added, high-tech performance aluminum alloy precision casting, such as computer hard drive, PS baseboard for printing, canning materials, fan blades for turbojet engine, etc.
The ceramic Foam Filter is surrounded by a Sealing gasket, laying between the filter and filter bowl, to prevent molten aluminum from leaking through an interface. AdTech’s filter adopts sealing gasket in 3 different types, fiber paper material, fiber cotton material, and expanding cotton material.
