ISO9001 Foundry Ferroalloy Sprue Bush Filter 10mesh Gravity Casting Aluminium Alloy Wheel

Aluminium Filtration Fabric Fiberglass Mesh filter is specially developed and used for filtration, turbulence reduction and flow distribution improvement of non‐ferrous alloys especially the molten aluminum. The Aluminium Filtration cloth product is weaved from E-glass fiberglass yarn with resin coating. The filter fabric can be soft or rigid in roll, cut pieces or molded shapes.

Fiberglass filter screen is a filter mesh made of fiber mesh cloth with various materials by impregnating resin and other bonding materials. The function of the fiber filter is mainly to prevent macroscopic inclusions from entering the cavity, and to slightly absorb fine inclusions. Its main features are low price and easy to use. Fiber filter screens for foundry can be divided into fiber filter screens for molten steel, molten iron, and molten aluminum according to different application scopes. According to different shapes, they can be divided into sheet, round, spherical, cap-shaped, cylindrical filters, etc.. 

The materials used are different, and can be divided into filters such as alkali-free mesh cloth and high-silica mesh cloth. Alkali-free mesh is made of aluminoborosilicate glass, and its alkali metal oxide content is less than 0.8%. High silica fiberglass mesh is made of high-silica glass fiber woven mesh after post-processing. It has excellent characteristics such as high temperature resistance, high tensile strength, and good adsorption performance. It is widely used in the production of casting filter mesh, casting filter net. The product standard of high silica glass fiber mesh is that the silica content is not less than 96%. Fiber filter screens for cast aluminium generally use alkali-free mesh cloth, and fiber filter screens for cast iron and cast steel generally use high silica glass fiber mesh cloth.
