The sintered mesh filter disc is an ideal filter element integrating filtering, washing, and drying functions. The main filter medium is multi-layer stainless steel sintered mesh, laser-cut into integral or split structures, offering high mechanical strength, excellent rigidity, and uniform pore distribution. Interlaced pore layers overcome the low strength, poor rigidity, and unstable pore shapes of regular wire mesh. Can be customized for different filtration environments and media, providing stable filtration precision, high efficiency, wear resistance, heat and corrosion resistance, and easy manufacturability, outperforming metal powder, cloth, ceramic, and fiber filter media. Suitable for liquid filtration in electronics, pharmaceutical, chemical, and petroleum industries.
