Fiberglass Fabric Filter Cloth is specially developed and used for filtration, turbulence reduction and flow distribution improvement of non-ferrous alloys especially the molten aluminium.

There are two types:

● One is white color and soft without any coating.

● The other is brown color with coating by special resin.

Fiberglass Fabric Filter Cloth Woven Process

Technical Data Parameter:

Widely used in automobile and motorcycle wheels, cylinder pistons, aluminum rods, aluminum materials, aluminum ingots, aluminum plates and precision casting of all types of aluminum alloy casting.

Aluminium Filtration Process by Fiberglass Filter Cloth

Application type:

● Filter cloth in roll (white & brown, without/with coating) : It can be fixed in the aluminum liquid flow tank, used for aluminum ingot, aluminum rod, aluminum strip and other continuous casting workshop to purify aluminum liquid.

● Cutting mesh (brown, coated with resin): Square, round, fan and other heteroideus mesh cutted just according to client’s requirements. Used for filtering aluminum castings and placed in the gating system.

● Cylinder, cap and other special shapes (brown or black, coated with resin or carbonized): used for low pressure casting, such as aluminum alloy wheels, engine cylinder head and so on.

● Smokeless (black carbonization treatment): no combustion, smokeless, low gas output during the filtration process, for high quality requirements of casting production, such as aluminum alloy piston.

New patented product "Smokeless and Odorless Filter Mesh" will gradually replaces similar products, especially metal filter such as stainless steel filter, Galvanized steel filter to removal of non-metallic inclusion in metal melt is of great technical and economic value to improve the yield of castings and the quality of castings.

Features and Functions:

● Effectively remove impurities, reduce turbulence and eliminate air bubbles from molten aluminium.

● Improving the quality of castings and reducing costs.

● Does not pollute the aluminum liquid and affect the chemical properties of the metal.

● The aluminium filtered by this mesh can be recycled again.

●  It is environment-friendly products

●  All shapes can be customized according to clients' requirements.

Key Points of Usage:

1. Use area of filter net: F1 = F2 / AxB

● F1: the cross-sectional area of the casting system. 

● F2: the original cross-sectional area of the casting system.

● A: the porosity of the filter screen, generally 50-60%. 

● B: the filtration rate of filter screen, generally 60-80%.

Therefore, the cross-sectional area of the casting system is generally 2-4 times that of the casting system without the casting net.

2. Position of filter screen:

● Place the filter under the sprue cup;

● Placed on the parting surface under the sprue;

● Three different positions on the lap surface of the runner.
