High Silica Fiberglass Filter Mesh for Molten Aluminum Steel Foundry Filtration

High Silica Fiberglass Filter Mesh for Molten Aluminum Steel Foundry Filtration

High Silica fiberglass filter mesh is weaved with high silica fiberglass yarn and coated with special refractory coating. It can effectively remove slag, refractory particles and non-metallic inclusions from molten metals. After special treatment, high silica mesh filters are capable of withstanding pouring temperatures up to 1620℃. High Silica fiberglass mesh is an ideal filter for in-mold filtration of gray, malleable, white, compacted grate 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 filtration, it also could be used for riser knock-off or de-gating knock-off. Investment casters have also placed the preformed cup shape filters in the wax mold gating system to filter metal at pattern entry. It is developed as a low cost but with rather filtration efficiency alternative to ceramic filters.
