Why are fiberglass filter mesh used in industrial casting production? What are the benefits?

In casting production, there are some quality problems of slag holes, sand holes, and gas holes for steel castings, iron castings, aluminum castings and other alloy castings due to various reasons. Therefore, there are great technical value and economic value for improving casting yield and quality that the non-metallic inclusions in the metal melt are removed.

The molten aluminum is easily oxidized in contact with the air to produce impurities such as oxide scale. At the same time, aluminum castings often have high quality requirements, so the use of filters is very effective.

1. The use of filters can improve the mechanical properties of the castings, increase the hardness of the castings, make the surface hardness uniform and improve the bending strength of the castings.

Change the graphite morphology of the casting, so that the graphite size is reduced, the thickness is thinner, and the shape is slightly curved.

Change the machining performance of castings and improve the processing efficiency.

Main varieties of fiberglass filter mesh are: molten aluminum, iron, steel, copper filter, casting filter, etc.

2. Change the machining performance of castings and improve the processing efficiency.

Compared with all various filters, the high temperature resistant fiberglass filter mesh does not affect the composition of aluminum alloy. The filtration effect is better because the fiberglass itself has the effect of absorbing impurities.

Because the casting filter mesh has the advantages of high temperature resistance, good mesh stability, convenient use, etc., it is also conducive to the recycling of molten metal waste ( the mesh is floated on the surface of the aluminum solution after the waste is returned to the furnace). High temperature resistant fiberglass filter cloth is an ideal filter material for high-grade aluminum alloy castings.

3. It not only has good properties, such as: high temperature resistance, ablation resistance and chemical stability, but also has good steel strength and resistance to metal melt erosion.

CANGENDAS Fiberglass mesh filter for molten aluminum is woven with special high-twist and high-strength alkali-free glass fiber yarn and special post-treatment, the temperature resistance can reach 900℃.

The application range is of aluminum, aluminum ingots, aluminum plates and aluminum alloy parts and other precision casting filtration, which can effectively remove bubbles, slag inclusions, etc. in the aluminum liquid, greatly improve product quality, is an economical material for filtering aluminum alloys.

CANGENDAS Fiberglass mesh filter can be used for all types of aluminum alloy casting, used in sand casting, mold, shell mold, drawing and investment casting. 

Used in low pressure casting can effectively remove impurities, reduce turbulence, eliminate air bubbles, thereby improving Casting quality and reducing production costs; meanwhile, CANGENDAS Fiberglass mesh filter does not pollute the molten aluminum and does not affect the chemical properties of the metal.

● At present, a large number of manufacturers use metallic barbed wire as a filter material, but due to the presence of a large amount of iron elements, the blanks waste parts containing the filter, gate and riser can only be treated as waste aluminum.

● But aluminum liquid filtered by Fiberglass mesh filter can be directly returned to the furnace for remelting, which greatly improves the reuse rate of waste aluminum and reduces the cost.
