Multi-layer sintered woven mesh is composed of multi-layer stainless steel wire mesh, which is special canlendering and sintering in vacuum oven, to create a new filter material with high strength and rigidity. Its interlaced mesh forms a uniform and ideal filtration structure. It has excellent performance such as excellent filtration precision,filtration resistance ,mechanical strength,wear resistance ,heat resistance,cold resistance and processability, it is more ideal for the demand for pressure strength and filtration precision uniform.
