Filter glass textiles for aluminum foundries

Filter glass textiles for aluminum foundries are essential components in the casting process, designed to improve metal quality and reduce casting defects. Typically made from fiberglass either untreated or with a resin finish these devices are placed within the gating system to trap impurities and solid inclusions present in the molten metal. The primary function of foundry filter glass textiles is to filter the molten aluminum as it flows into the mold cavity. Specifically, they:

Capture oxides, dross, and non-metallic inclusions, preventing them from becoming trapped in the final casting
Even out metal flow, reducing turbulence and splashing
Improve the surface and internal quality of the parts by minimizing porosity and structural defects

The result is a more reliable final product with superior mechanical properties and reduced production waste.

Foundry filter glass textiles are available in various formats, including 1000 mm wide rolls, rolls of customizable heights, and custom-cut pieces (rectangles, squares, etc.).

Filter glass textiles are an indispensable solution for aluminum foundries aiming for high quality standards. By eliminating impurities and optimizing metal flow, they contribute significantly to the efficiency and reliability of the entire production process.
