The standard five-layer sintered woven wire mesh is a new filtering material with high strength and overall rigidity, which is made of multi-layer metal woven wire mesh and manufactured by special laminated pressing and vacuum sintering process. The mesh holes of each layer mesh are interlinked to form a uniform and ideal filtering structure.It not only overcomes the shortage of low strength, poor rigidity and unsteady shape of mesh, but also can match and design reasonably the void size, permeability and strength characteristics of the material. https://www.nayushiye.com/products/sintered-metal media/55.html
