SIC (silicon carbide) ceramic foam filters are developed and manufactured for the filtration of  for the filtration of nodular cast iron, gray cast iron, ductile iron, aluminum, copper and other alloy metal liquid.

As the most advanced filter type with the higher filtration efficiency, It can effectively reduce inclusions and turbulence of molten metal, ensuring purified molten metal goes into the mould cavity with improved flow rates.

Using the unique formula and manufacturing process, SIC ceramic foam filters have the excellent thermal shock, chemical and high temperature resistance up to 1530°C.

Silicon carbide ceramic foam filter adopts German imported polyurethane foam sponge as the carrier, the slurry which mainly contains silicon carbide is extruded into the foam sponge, and then extrude slurry, the remaining slurry coated around the foam fiber is dring, roasting and sintering at high temperature, polyurethane is decomposed by heat, foam shaped ceramic products are left, namely, silicon carbide foam ceramic filter.

Key Features of Silicon Carbide Foam Filter:

■ Exceptional Thermal Stability: Withstands temperatures up to 1500°C, making it ideal for filtering molten nodular cast iron, gray cast iron, and copper without risk of degradation.

■ High Filtration Efficiency: The open-cell structure of the SiC foam provides an extensive surface area, effectively trapping non-metallic inclusions and slag particles, resulting in cleaner metal.

■ Superior Mechanical Strength: Robust enough to endure the mechanical stresses encountered during the pouring process, ensuring consistent performance and reliability.

■ Enhanced Metal Quality: By removing impurities, the SiC foam filter improves the mechanical properties, surface finish, and overall quality of the cast metal, leading to higher-quality end products.

■ Thermal Shock Resistance: Designed to handle rapid temperature changes without cracking, ensuring uninterrupted filtration during the casting process.

Silicon Carbide Foam Filter Advantages:

■ Improved Casting Yield: Reduction in inclusions and impurities minimizes defects, leading to higher yields and fewer rejected parts.

■ Cost-Effective: Reduces the need for extensive post-casting machining and rework, saving time and production costs.

■ Ease of Integration: Designed for compatibility with existing gating systems, allowing for easy implementation without major modifications.

■ Environmental Benefits: By enhancing the quality of the cast products, our SiC foam filter contributes to less waste and more efficient use of resources.
