Multi-layer metal sintered mesh is a new type of filter material with high strength and overall rigidity, which is made of multi-layer stainless steel wire mesh after special laminated pressing and vacuum sintering. The meshes of each layer are interlaced and form into a uniform and ideal over-structure. It has excellent filtration accuracy, filtration resistance, mechanical strength, wear-resistance, heat resistance, cold resistance and machinability. It is ideal for filtering with uniform compression strength requirements and filtration accuracy requirements and widely used in petrochemical, nuclear power, Synthetic fiber, film, food, pharmaceutical, aerospace and environmental protection industries.
