Product Description

High silica fiberglass mesh filter 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 silica mesh filters are capable of withstanding pouring temperatures up to 1620ºC. 

Silica mesh filters are 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 also be used for riser knock‐off or de‐gating knock‐off. Investment casters have also placed the preform cup shape filters in the wax mold gating system to filter metal at pattern entry.

Features
• Cost effective and easy to use, easy fit existing pattern equipment
• Eliminates inclusions created by ceramic chips
• Improves metal fluidity and distribution, reduce turbulence
• Removes micron sized inclusions and impurities
• Minimize gating system to reduce cost
• No need for pre‐Heat, non‐chilling
• Unique function as riser or gating parts knock‐off removal
