It is made of special ultra-thin cutting blades and beams, and its slot width (0.2-0.5mm). The slit section is rectangular, trapezoidal (trapezoidal angle is 3-8 degrees) and special shape (round hole) and other forms, which can ensure the permeability is 0.5%-10%. The arrangement of the gap can be processed according to user requirements.
