Product Description

Aluminum water filter is cast aluminum glass fiber filter, using high twist high strength alkali free glass fiber woven and after special post-treatment, the surface coated with high temperature resistant paint, high temperature resistance up to 900℃, very suitable for aluminum water filtration. Aluminum water filter is widely used in automobile and motorcycle wheel hub, cylinder piston, aluminum rod, aluminum, aluminum ingots, aluminum plate and aluminum parts of the casting filter. Aluminum water filter can effectively remove bubbles and slag in liquid aluminum, greatly improving product quality. Aluminum liquid contact with air is easy to be oxidized and produce impurities such as oxide skin, while aluminum casting

Aluminum water filter is cast aluminum glass fiber filter, using high twist high strength alkali free glass fiber woven and after special post-treatment, the surface coated with high temperature resistant paint, high temperature resistance up to 900℃, very suitable for aluminum water filtration.

Aluminum water filter is widely used in automobile and motorcycle wheel hub, cylinder piston, aluminum rod, aluminum, aluminum ingots, aluminum plate and aluminum parts of the casting filter.

Aluminum water filter can effectively remove bubbles and slag in liquid aluminum, greatly improving product quality.

Liquid aluminum in contact with the air is easy to be oxidized and produce impurities such as oxide skin, and aluminum castings often have high quality requirements, so the use of filters is very effective.

Aluminum water filter can be used for most types of aluminum alloy casting, in sand casting, permanent mold, shell mold, pull mold and investment casting used, can effectively remove impurities, reduce turbulence, remove bubbles, thereby improving casting quality and reducing production costs.

Aluminum water filter does not pollute liquid aluminum, does not affect the chemical properties of the metal, there are still a large number of manufacturers use wire mesh as a filter material, but due to the presence of a large number of iron elements, containing the filter blank waste parts, gates and risers can only be treated as waste aluminum.

The use of aluminum water glass fiber filter can be directly remelted in the furnace, thus reducing the cost.

Glass fiber is a very fine fiber made of molten glass, which has many advantages such as insulation, heat resistance, corrosion resistance and high mechanical strength.

The main components of glass fiber are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide and so on.

Glass balls or waste glass as raw materials through high temperature melting, drawing, winding, weaving and other processes, made of various products.

The diameter of glass fiber monofilaments is usually equivalent to 1/20 to 1/5 of a human hair, and each bundle of fiber filaments consists of hundreds or even thousands of monofilaments.

Usually used as reinforcing materials in composite materials, electrical insulation materials and thermal insulation materials, circuit board, etc., are widely used in many fields.


Product features:

Alkali-free glass fiber filter has the advantages of high strength, good toughness and impact resistance, and can be cut and bent into various specifications and styles at will, flexible and free combination, suitable for casting aluminum process in various environments


Advantages:

Low cost, easy to use

The mesh is smooth and the filtering effect is good

Reduce turbulence and reduce bubbles

Waste reduction

Remove oxides and slag inclusion

Improve metal distribution


Precautions for use:

The filter should be placed close to the sprue as far as possible, so as to block the floating sand in the sprue more.

The filter is recommended to be placed on the parting surface of the lap above and below the runner, so that the operation is simple and the effect is good. At this time, the runner in the direction of the water inlet is as far as possible in the upper box, which is conducive to the floating of inclusions and the resistance to the hot metal is reduced.

When the runner cannot be overlapped for some reason, the filter can be placed on the cross section of the runner or the inner runner, and the runner must be in the upper box at this time. Because the inclusions flow in the upper part of the metal liquid, the lower gap of the net does not affect the slag resistance, but when the cross-sectional area of the runner is too large or too wide, the filter will be deformed at high temperature, resulting in the lower gap is too large, affecting the slag blocking effect.

The placement of the filter in the pouring system should be fixed and firm to prevent the impact displacement of the metal liquid from affecting the slag blocking effect. Generally, the part of the filter screen that is pressed by molding sand is: the wet pouring system presses 15mm on each side, if it is buried in the runner, each side can be slightly smaller, and the dry type presses 20-30mm on each side.
