High Silica Fiberglass Filter Mesh For Steel Iron And Copper

High-silica fiberglass filter mesh is a woven, high-strength filtration fabric produced from high-silicon glass-fiber yarns. The yarns are twisted and interwoven, treated with a specially formulated heat-resistant coating, and finished through high-temperature composite processing, cutting, sewing and decontamination to produce durable filter meshes suitable for foundry use.

Key features

• High thermal stability: thick variants withstand pouring temperatures up to 1620°C.
• High-silica composition and heat-resistant coating for improved chemical and thermal resistance in contact with molten metals.
• Robust mechanical construction: twisted high-strength glass fiber yarn with reinforced sewing and edge finishing for repeated handling and use.
• Available in a variety of shapes and sizes; can be supplied as flat sheets, cups or custom-cut pieces for in-mold or gating-system installation.

Primary applications

• In-mold filtration of molten steel and small-scale steel castings
• Filtration of iron grades (gray, malleable, white, compacted graphite, ductile)
• Filtration of non-ferrous alloys including copper and aluminum
• Removal of slag, refractory particles and non-metallic inclusions from molten metal
• Use as riser knock-off or de-gating knock-off elements
• Investment casting: cup-shaped filters placed in wax molds to filter at pattern entry

Benefits for foundries and casting operations

• Improves casting quality by reducing inclusions and slag-related defects
• Reduces downstream cleaning and rework by capturing particulate contaminants in the melt
• Adaptable to different gating systems and casting processes
• Customizable geometry for specific mold and pattern requirements

Supply and customization

• Can be manufactured to customer specifications for shape, thickness and dimensions
• Suitable for use across ferrous and non-ferrous foundry applications

If you require custom shapes, specific mesh densities or particular edge/seam treatments for automation or manual handling, specify your requirements (shape, dimensions, operating temperature) so the mesh can be produced to match your casting process.
