Aluminium Filteration

This product is woven with specific high-twisted yarn and then treated; the heat-resistance temperature of this product can be above 800 C.deg if with special treatment. It is an ideal material to filter aluminum in melting and casting process. Series nettings can be provided, having advanced technology and stable quality. They are widely used for filtration of molten aluminium in foundry of automobile wheel motorcycle wheel cylinder piston as well as aluminium alloy parts.
Fiberglass Fabrics have found an interesting application for filtration and uniform distribution of molten aluminium. Oxides are generated when molten aluminium comes in contact with oxygen in air. Chemical reactions occur at high temperatures particularly during melting, be it primary melting, foundry casting or recycling. Oxides must be removed before the metal is cast and this is the stage where fiberglass fabrics and articles made there from are used to give better casting results. The simplest form of application is directly as a cut piece of filter fabric. Evolved shapes stitched from glass fabrics like Combo Bags, Channel Bags, Spout Socks, Funnels, and Launder Socks are also used. These articles help to reduce turbulence, filter oxides as well as improve temperature distribution throughout the ingot.
These fabrics are treated with resinous chemicals to stabilize the weave. Molten metal is filtered through this mesh. Number of yarns used will determine the strength of the fabric during filtration. This will also control the amount of flow of liquid aluminium. Smoke free fabrics are also available as a thermal treatment is imparted on the fabric.
