Application for Ceramic Foam Filter
AdTech’s ceramic foam filter plate is produced basing on carrier with solid reticular structure and combined organic foam pores. The producing procedure is as below, put carrier into the thixotropic alumina slurry, adopt square to center correcting automatic extrusion process, so that slurry evenly deposits in foam skeleton of carrier, after drying solidification, then carrier will turn into final product by roasting formed under 1180 ℃ high temperature. Filter is installed in the filter bowl for filtrating impurity 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.
Advantages for Ceramic Foam Filter
Filtration Rate of Ceramic Foam Filter
Filtration Rate of our Ceramic Foam Filter is based on filter’s pore size, inclusion’s size, type (density, wetness performance), and flow speed of molten metal through filter.

Sealing gasket for Ceramic Foam Filter
Ceramic filter is surrounded by Sealing gasket, laying between filter and filter bowl, to prevent molten aluminum leaking through interface. AdTech’s filter adopts sealing gasket in 3 different types, fiber paper material, fiber cotton material, expanding cotton material.
