High silica fiberglass fabric filter (Thick Type)

High silica fiberglass fabric filter (Thick Type) is weaved by high silica fiberglass yarn and coated with special refractory coating.

Made from specially treated silica yarns, the thick type silica mesh filters are capable of withstanding pouring temperature up to 1620℃.

It can effectively remove slag, refractory particles and non-metallic inclusions from molten metals.

Silica mesh filter are 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 systerm to filter metal at pattern entry.

Features of High Silica Fiberglass Fabric Filter Mesh:

A. High temperature & corrosion resistance

B. High intensity & high pass rate

C. Good filtration & purification effect

D. Diverse sizes & Customized service

Application of High Silica Fiberglass Fabric Filter Mesh For Steel Iron And Copper

The High Silica Fiberglass Fabric Filter Mesh For Steel Iron And Copper are made by special weaving and post-processing. Products have become a series, advanced technology, stable quality. Widely used in automobiles, motorcycle hubs, cylinder pistons, aluminum rods, aluminum ingots, aluminum plates and all kinds of aluminum alloy parts casting filters.

High Silica Fiberglass Fabric Filter Mesh Key Points of Usage

1. Use area of filter net: F1 = F2 / AxB

● F1: the cross-sectional area of the casting system. 

● F2: the original cross-sectional area of the casting system.

● A: the porosity of the filter screen, generally 50-60%. 

● B: the filtration rate of filter screen, generally 60-80%.

Therefore, the cross-sectional area of the casting system is generally 2-4 times that of the casting system without the casting net.

2. Position of filter screen:

● Place the filter under the sprue cup;

● Placed on the parting surface under the sprue;

● Three different positions on the lap surface of the runner.
