Fiberglass Filtration Mesh

Fiberglass Filtration Mesh

Fiberglass Mesh Filter

Fiberglass Filter Mesh Sheets are made of high temperature resistant fiber, woven and processed by special technology. 

There are kinds of products series with advanced technology and stable quality. 

Application: Filtration of molten aluminium.

Compared with other types of filters, fiberglass casting filter is cheap, easy to use, does not change the metal composition of the casting, has good slag filtering effect and low gas generation. 

In addition, it also has high temperature resistance, ablation resistance,good chemical stability, resistance to metal melt erosion and good steel strength.


In casting production, steel castings, iron castings, aluminum castings and other alloy castings are prone to quality problems such as slag holes, sand holes and gas holes due to various reasons. Therefore, the 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.

Fiberglass Mesh Filter  

Filtration of molten aluminum is a critical process in the aluminum casting and manufacturing industry. Molten aluminum, while being processed and transferred, can contain various impurities and non-metallic inclusions that can adversely affect the quality of the final aluminum products. The use of fiberglass mesh filters in this application helps ensure the production of high-quality, clean aluminum products.

Process Overview:

Molten aluminum is often subjected to various processes such as melting, refining, alloying, and casting. During these processes, impurities like oxides, slag, dross, and other non-metallic particles can get entrapped in the molten aluminum. If these impurities are not effectively removed, they can lead to defects in the final aluminum products, compromising their mechanical properties and overall quality.

Fiberglass filter mesh sheets features:

◆ Remove bubbles, oxides, dust and other miscellaneous objects and harmful impurities, eliminate air -eye, slag eye, and improve the yield and appearance quality and inherent quality of the casting.

◆ Improve the mechanical properties of the casting after filtering, such as the stiffness, surface, and bending strength of the casting.

This Fiberglass filter mesh sheets is used by a casting plant for filtering metal melting water, such as aluminum water, iron, and steel. In order to adapt to various applications of castings, we can make alien nets for casting filters. The shape can be like discs, cups, small baskets, etc. We can provide custom sizes according to your requirements.

Fiberglass Mesh Filter is an ideal filter material for various metal melts. It can also be used for the filtration of chemical corrosive liquids and high temperature gases.

Fiberglass filter mesh sheets can be made in various sizes and shapes to fit different filter housings and systems. They can also be designed to meet specific filtration efficiency, temperature resistance, and chemical resistance requirements.

Filtration with Fiberglass Mesh Filters:

Fiberglass mesh filters are employed at different stages of the aluminum manufacturing process to capture these impurities and ensure a higher level of purity in the molten aluminum. 

Here's how they are used:

①Casting Furnace: In the casting furnace, where aluminum is melted, fiberglass mesh filters can be placed at the outlet of the furnace to catch larger impurities like dross and slag. This prevents these impurities from entering the casting mold and creating defects in the final product.

②Transfer Channels: As molten aluminum is transferred from the furnace to the casting molds or other processing units, fiberglass mesh filters can be installed in the transfer channels. These filters capture finer impurities that might have been missed in the furnace filtration. This step helps ensure that the molten aluminum remains clean and free from contaminants during the entire transfer process.

③Casting Molds: Fiberglass mesh filters can also be integrated into the gating system of the casting molds. This placement captures any remaining impurities before the molten aluminum solidifies and takes the shape of the mold. It contributes to producing aluminum products with smooth surfaces and consistent properties.
