Fiberglass Filtration Mesh

Fiberglass Filtration Mesh

Fiberglass Cap Filter For Aluminium Filtration

The Cap-Style Fiberglass Filter Mesh

● Weaved with special high-twist & high-strength alkali-free fiberglass yarn

● Coated by special resin

● Special post-treatment under high temperature carbonized

● The Max. temperature resistance can be reached 900 ℃.

● Smokeless & Odorless & Flameless during whole use process

With one or two staples or not, up to clients' need

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.

● It can effectively remove impurities, reduce turbulence and eliminate air bubbles, thereby improve the quality of castings and reduc costs.

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

● Aluminum waste containing the cap filter mesh, aluminum liquid from sprue and the riser can be directly returned to the furnace for remelting, greatly reducing costs.


As a filter equipment often used in industrial production, cap filter plays an important role in metal smelting industry.

The use of cap filter, can effectively reduce more than half of the slag, impurities caused by the waste phenomenon. This is also the main reason for the wide use of filters, is also the main trend. 

Secondly, it can effectively remove non-metallic inclusions in liquid metal, which is also a big use of cap filter. Through the use of filter, can significantly improve the casting structure and mechanical properties, so that the casting quality is higher, better quality, reduce the rejection rate, reduce tool wear.

Casting filter is not only used to reduce casting porosity, but also can effectively reduce casting surface defects and increase process yield. It can effectively screen and adsorb small pre-slag, so that the quality of metal castings is better, the performance is better, to create high-quality castings.

Features and Functions:

● Carbonized by High Temperature
