Import Ceramic Foam Filter — Buy in Bulk from Supplier in China

The Ceramic Foam Filter from King Filter Engineering Co., Ltd. is engineered for high-temperature aluminum casting environments, featuring a lightweight, open-cell ceramic structure designed to remove inclusions from molten metal. The product is optimized for use in aluminum smelting operations, with a maximum service temperature of 1400°C. Filters are available in customizable sizes to fit varying mold geometries, and the material formulation is based on alumina with zirconia reinforcement to enhance durability under thermal cycling.

Typical pore densities range from 10 to 30 PPI, with the 20 PPI variant being most common in aluminum foundries. The filter’s low bulk density, approximately 0.25 - 0.35 g/cm³, allows for easy handling and reduces the risk of breakage during installation. Unlike some coated filters, this product is not surface-treated, relying on its intrinsic porosity for filtration. The absence of organic binders ensures no carbon residue is introduced into the melt, supporting cleaner castings with fewer surface defects.

This filter is primarily used by aluminum die-casting and sand-casting facilities in automotive and industrial component manufacturing. Buyers often require consistent batch-to-batch performance for automated production lines. Packaging is typically in protective cartons with internal dividers. Trade terms such as FOB and CIF are available, but exact MOQ and lead time are not disclosed. Buyers should request sample testing under their specific pouring conditions to validate performance.
