Ready to Revolutionize Your Casting Quality With Foundry Filters?

Metal Filtration Technology Development Process

Foundries and metal casting operations face persistent challenges from non-metallic inclusions, oxides, and slag that compromise final product quality, increase rejection rates, and limit production efficiency. Traditional foundry practices have struggled to effectively address these contaminants, especially as manufacturing standards continue to rise.

Metal filtration technology has made significant progress over the past few decades. Each generation of metal filtration systems has significantly improved metal purity, casting quality, and production efficiency, representing one of the most significant technological advancements in the foundry industry.

From the initial fiberglass mesh filters to honeycomb ceramics and now to advanced ceramic foam filters, each generation has brought new improvements in temperature resistance, filtration efficiency, and mechanical strength.

Filtration Systems

Today’s ceramic foam filters – available in silicon carbide, zirconia, and alumina filters – offer unprecedented levels of inclusion removal, with filtration efficiency rates reaching 95%. This translates directly to measurable business outcomes: scrap rates reduced by up to 35%, improved surface finish, enhanced mechanical properties, and simplified gating systems.

Our comprehensive range covers all three generations, ensuring you have the right solution regardless of your specific metal casting application, from aluminum automotive components to high-temperature steel castings.

Metal Filtration Types

Different metals, casting methods, and quality requirements demand specialized filtration approaches. A one-size-fits-all strategy fails to address the unique characteristics of various molten metals and their specific inclusion types. Our comprehensive filtration portfolio spans three generations, each offering specific advantages for different casting applications:

Other Foundry Filter Types

Different metals, casting methods, and quality requirements demand specialized filtration approaches. A one-size-fits-all strategy fails to address the unique characteristics of various molten metals and their specific inclusion types. Our comprehensive filtration portfolio spans three generations, each offering specific advantages for different casting applications:

FM-09 SIC Filter

The high-performance ceramic filter designed for the aluminum alloy casting industry is made of silicon carbide (SiC) high-temperature resistant material sintered through a special process. It can efficiently filter non-metallic inclusions in aluminum alloy molten metal.

FM-02 Reinforced SiC Filter

FM-02 filter has higher strength and higher temperature resistance than ordinary ceramic foam filter, and can withstand heavier casting and higher temperature casting. It is mainly suitable for harsh environments such as filter plates placed at the bottom of the sprue or casting with heavy weight.

FM-08 Magnesium Ceramic Filter

It performs better when processing titanium, magnesium alloy and other metals, and can effectively filter non-metallic inclusions in molten metals. It has good thermal shock stability and mechanical strength, and can adapt to drastic temperature changes.

Filter Applications

Through continuous innovation in material technology, our filtration solutions have expanded from the foundry industry to the environmental protection field, and are committed to providing more efficient and sustainable product support for industrial manufacturing and green life.
