What is Fiberglass Mesh Filter?

Fiberglass mesh filters can effectively remove slags, refractory particles and non-metallic inclusions from molten metals to ensure the production of high-quality castings.

The filters are made of specially treated silica fiberglass yarn and coated with special resin. They are brown with resin coating or black with smokeless carbonized treatment.

The mesh filter acts as a barrier, capturing and trapping unwanted particles, such as slag, sand, or other contaminants, that can compromise the integrity and performance of the final cast products. By effectively filtering the molten metal, the casting filter screen promotes smoother flow, reduces turbulence, and enhances the overall casting quality.

With its durable construction and efficient filtration properties, the casting filter screen is an indispensable tool for achieving consistent and reliable casting results in various industries, including automotive, aerospace, and manufacturing.
