Combo / Channel Bags

Combo / Channel Bags are fabricated from fiberglass filter fabrics for use in molten aluminium filtration and distribution during casting operations. They are designed to help remove oxides generated when molten aluminium comes into contact with air, while supporting improved casting conditions.

These shaped filtration products are stitched from glass fabrics and are used to reduce turbulence, filter oxide inclusions and improve temperature distribution through the ingot during aluminium casting. The fiberglass fabrics are treated with resinous chemicals to stabilise the weave, allowing molten aluminium to pass through the mesh during filtration.

Filter fabrics are available in plain and leno weave constructions. Plain weave is used where finer filtration is required, while leno weave provides a more open mesh with greater dimensional stability. Fabric widths of up to 1500 mm are available, along with cut pieces in different sizes and shapes.

Applications:

• Molten aluminium filtration
• Oxide removal during casting
• Aluminium ingot casting
• Primary aluminium melting
• Foundry casting
• Aluminium recycling operations
