Product Description :
SIC Ceramic Foam Filter is a kind of effective molten metal filter which is mainly designed for filtering impurities from ductile iron . With their excellent resistance to attack and corrosion from molten iron liquid, they can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. SiC Ceramic Foam Filters is available in all standard dimensions and different thickness. The most common porosity are PPI 10, 20 , 30 and 40; higher porosity are available upon request. Custom-made cut-to-size filters are also possible.
Advantage :
·Remove impurities and improve the purity of molten metal efficiently
·Reduced amount of scrap
·Reduced costs of finishing operations
·simple design and gating system
·Improved mechanical properties of castings
·Improved precision of dimensions and shapes of castings
