Foundry Filter Mesh for Metal Filtration

Foundry enterprises commonly face high scrap rates due to slag inclusion defects in castings. Traditional ceramic filters, while somewhat effective, are fragile, and increase production costs. Our FM-07 Series Fiberglass Molten Iron Filter Mesh utilizes patented high-silica glass fiber technology, effectively intercepts oxide inclusions, sand particles, and slag in molten iron. The special fiber weaving process maintains structural stability at temperatures up to 1450°C without melting or deformation.

Compared to ceramic filters, fiberglass filter mesh is lighter, easier to install, and due to its flexibility. The product has passed ISO 9001 quality certification, exported to over 50 countries including Turkey, USA, and India, serving more than 800 foundry manufacturers.
