Foam Filters With Gasket

Foam Filters With Gasket

Foam Filters With Gasket takes reticular structure and organic foam as carrier and put carrier into the thixotropic Al2O3 slurry adopt square to center correcting automatic extrusion process. Slurry evenly deposits in foam. After drying solidification, carrier will turn into final product under 1180℃ , specially used for aluminium precision casting.

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.

Foam Filters With Gasket 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
Adopt adsorption principle for Ceramic foam filter, can effectively remove big piece inclusions in molten aluminum, and effectively adsorb tiny inclusions.
No broken bits drop out, effectively reduce the pollution of molten aluminum.
Superior thermal shock resistance, improve erosion resistance ability of molten metal.
Automatic flow production，3 calibration procedures，precision size，fit the filter bowl tightly.
Improve the surface appearance and performance, purify molten aluminum.
