About Us 

Our company is China's first manufacturer to adopt CNC drilling for 1mm aperture stainless steel sieve plates. Since the successful production of the first 1mm aperture sieve plate in 2008, we have a 17-year history in this field.

We produce high-precision stainless steel sieve plates using mechanical drilling technology. We can process straight holes, tapered holes, step holes, etc., on various stainless steel materials including 304, 316, 904, 254SMO, 2507, 2205 (1.4462), 201 (1.4372), 2101, and TA1. The minimum aperture is 0.1mm, and the maximum product size is 2600*15000mm. Our products feature uniform hole distribution, with hole position deviation of small holes controlled within 0.05mm and aperture deviation within 0.015mm. The sieve plates have low stress concentration and long service life. The hole wall roughness is 1.6μm, and the smooth hole wall is the key to preventing clogging during the filtration process.
