More Filter Production Scenarios
In our modern production facility, alumina ceramic foam filter plates are precision-manufactured to provide efficient filtration solutions for the aluminum casting industry. High-quality alumina powder is uniformly mixed with a special binder, then formed into a three-dimensional porous structure through advanced processes. This structure is then sintered at high temperatures to ensure high strength, high-temperature resistance, and excellent chemical stability.
Each alumina foam filter plate undergoes rigorous quality inspection. Its uniform pore structure effectively traps impurities, slag inclusions, and bubbles in the aluminum melt, significantly improving the purity and mechanical properties of castings. Our alumina foam filter plates are widely used in aluminum alloy casting, automotive parts, aerospace, and other fields, helping customers achieve high-quality aluminum castings with their superior filtration efficiency and reliability.
