High Silica cap-style fiberglass mesh filter is woven by high silica fiberglass yarn and coated with special refractory coating. The maximum temperature resistance can reach up to 1620℃. 

It is widely used in 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. 

The cap-style high silica fiberglass casting filter mesh is produced by heat resistance fiber in specific techniques and after-treatment. With features of lower cost, convenience to use, no impact on the element of metal casting, good efficacy on filter residue, heat resistance, flame resistance, this casting filter mesh is an ideal material for various liquid metals. High silica fiberglass also can be used on the filtering chemical corrosion liquid and High-temperature gas.

Application:

● Silica mesh filter 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.

Fiberglass cap filter production process

Why are Cap Filters so widely used?

First of all, it is imperative to reduce the waste of resources in the metal industry. It 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, also the main trend.

Secondly, it can effectively remove non-metallic inclusions in liquid metal, which is also a big use of cap filter. It 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.

Thirdly, Cap 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.
