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 metal. 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..jpg)
Product Applications:
-- 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.
Product Characteristics:
● Cut pieces for riser sleeves, bottom or across ports in walls.
● Cut pieces to provide a weakened plane for riser knock-off.
● Cup shapes for investment casting.
● Cut pieces for in mold filtration like sand casting, gravity casting, etc.

Storage:
High Silica mesh should be stored in its original packaging in a dry and cool place. Best conditions are at temperatures from 15 to 35°C and humidity between 35 and 65%. If no special requirements, it should be stored in cool and dry place. Don’t open the package before using to prevent absorbing moisture.
To ensure safety and avoid damage to the product, the pallets should not be stacked more than three layers high, when the pallets are stacked in 2 or 3 layers, care should be taken to correctly and smoothly move the top pallet.
