ZrO2 Ceramic Foam Filter

Introducing our premium ZrO₂ Ceramic Foam Filter, the ultimate solution for achieving unparalleled purity in your most demanding casting applications. Engineered with high-purity Zirconia (ZrO₂), this filter is specifically designed to withstand extreme temperatures and aggressive molten steel environments. Its three-dimensional, open-cell foam structure acts as a deep-bed filter, effectively capturing both large and microscopic inclusions like slag, oxides, and non-metallic particles. The result is significantly improved casting quality, with enhanced mechanical properties, superior surface finish, and a drastic reduction in defects such as inclusions and pinholes.

We offer extensive customization. Filters are available in standard square and round shapes. Dimensions can be customized starting from 30mm x 30mm (or 30mm diameter) with thickness options beginning at 10mm. Common standard thicknesses include 10mm, 20mm, 22mm, 25mm, and 30mm. We also manufacture custom, non-standard shapes to fit unique gating designs. For reference, our standard DT-3 model square sizes range from 40x40mm to 100x100mm (22mm thick), and round sizes from 40mm to 90mm in diameter.

Manufactured by Shanxi Dingtai Yinrui Filter Manufacturing Co., Ltd., a high-tech enterprise founded in 2016 with deep roots in filtration since 1997. Our 10,000m² facility is equipped with dedicated production lines, including a specialized Zirconia Ceramic Foam Filter line. We are ISO 9001:2015 certified, and our products meet the GB/T25139-2010 national standard.

Filters are carefully packed in inner cartons and secured on export-grade plywood pallets for safe international transport. We ship globally via sea or air freight.
