Description

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 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 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.





Product Features:

• Low cost and easy to use.
• Improves fluidity and metal distribution.
• Removes micron sized inclusions and impurities.
• Can be used with existing pattern equipment.
• Eliminates inclusions created by ceramic chips.
