Professional Manufacturer and Exporter of Fiberglass Mesh Filter In China

Nowadays, fiberglass filter mesh is adopted to filter and purify metal liquids by casting industries.

Due to the characteristics of cheap cost, simple production and convenient use, it has become a more commonly used casting auxiliary material.

Fiberglass filter mesh is made of various materials fiberglass cloth by impregnating resin and other bonding materials. The main function is to block macroscopic inclusions into the cavity, and slightly adsorb small inclusions.

● According to the different scope of use, it can be divided into liquid steel, liquid iron, liquid aluminum applications. 

● According to the different shapes, it can be divided into flake, round, spherical, cap, barrel, etc.

● According to the different materials used, it can be divided into alkali-free mesh cloth, medium alkali mesh cloth, high silicon oxygen mesh cloth and other filters.

● Non-alkali mesh is generally used for casting aluminum, high silicon oxygen mesh is usually used for casting iron and steel.

Hebei CangChen is always devoting ourselves to research & development, production, sales such serious of fiberglass filter meshes.

For now, there are the following fiberglass filter meshes types for molten aluminum, iron(copper) and steel filtration.

1. "Smokeless & Odorless & Flameless" Fiberglass Filtration Mesh For automobile and motorcycle wheels, cylinder pistons

Woven with special high-twist & high-strength alkali-free fiberglass yarn, coated with special resin, carbonized by high temperature and special post-treatment. The maximum temperature resistance can reach 800 ℃.

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.

New patented product "Smokeless & Odorless & Flameless" Fiberglass Filtration Mesh will gradually replaces similar products(metal types) 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.

According to the different shapes, it can be divided into flake, round, spherical, cap, barrel, etc.

2. TF Combo Bag for large Dia. aluminum ingot/billet/ slab.

Fiberglass thermally fused shunt combo bag, simply named TF Combo Bag, which is weaved by special high-twist & high-strength alkali-free fiberglass yarn, special post-treatment, coated with resin and carbonized by high temperature. its withstand temperature up to 1000 °C.

Main Features:

● New environmental protection material, does not burn during whole use process, no harm to human body.

● Advanced production equipment, warp and weft standard for base cloth, high temperature resistant coating mesh uniform, the finished product is exquisitely made without burrs.

● Both sides of the bag adopt square hole fixing device technology, more convenient operation and improve the working rate.

● Much tighter fabric surround the small fiberglass woven frame inside.

Application:

● Apply to filter and evenly distribute molten aluminum in molds.

● Apply to filter large diameter aluminum ingot and billet, rectangular aluminium slab, and aluminum-alloy casting parts.

● Used in sand casting, permanent mold, shell mold, draw mold and investment casting, which can remove impurities, reduce turbulence, eliminate air bubbles, thereby improve casting quality and reduce production costs.

3. High Silica Fiberglass Filter Mesh for Iron and steel liquid

High silicon oxide fiberglass: The main component is over 96% pure silica, which has extremely high heat resistance and ablation resistance. Its continuous temperature resistance can reach 1000℃, and its short-term temperature resistance can reach 1400℃. High silicon oxide fiberglass has good thermal shock resistance and can maintain strength and elasticity at high temperatures.

High Silica Fiberglass Filter Mesh is weaved by high silica fiberglass yarn and coated with special refractory coating. It can effectively remove slag, refractory particles and non-metallic inclusions from molten metals. Made from specially treated silica yarns, the thick type silica mesh filters are capable of withstanding pouring temperature up to 1620℃.

High Silica Fiberglass Filter Mesh is ideal for in-mold filtration of gray, malleable, white, compacted graphite and ductile cast irons, as well as non-ferrous aluminum and copper-based metal alloys and many types of small scale steel casting filtration.

Besides the function of molten metal filters, it could be also used for riser knock-off or de-gating knock-off. Investment casters have also placed the perform cup shape filters in the wax mold gating system to filter metal at pattern entry.
