Silica Fiberglass Filter Mesh For Steel Iron And Copper Filtration

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.

High Silica Fiberglass Filter Mesh is with extremely high flexibility, economical and practical, easy to use, high humidity, excellent resistance to impact, uniform grid, good overflow effect.

Due to its outstanding humidity and flexibility, it can also be used as a riser or a partition in the casting system.

After the liquid solidifies, it can be easily disconnected at the placement position, which can significantly reduce the cost of removing the riser and the casting of excess parts.

Why the traditional metal wire mesh filters are not good for LPDC castings?

Galvanized steel or iron wire mesh filters are at present commonly used for low pressure castings filtration, Especially for aluminum alloy wheels. Wire mesh filters are cost effective, with good strength and flexible on shapes and sizes.

Now there is a new and better material to perfectly replace it due to the disadvantages of wire mesh.

Using wire mesh filter, there will be largely Fe element added to the aluminum castings and this will lower the castings mechanical strength, especially for high quality standard, this means critical. For risers containing wire mesh filters after solidification, it can not remelted directly to furnace, even after the treatment. The direct cost is the risers had to be sold as scrap. lt's great waste.

The integrity of the weave pattern is maintained by the use of phenolic resin, and by the use of leno or Plain construction in high density. Regular coating and carbonized treatment are both available.
