Microetched screens in stainless steel
Fine MicroEtch Screens in stainless steel are manufactured by photoetching which lets designers specify straight or tapered holes. Such features facilitate liquid filtration and back-flow cleaning. Hole sizes can range from 0.003-in. diameter and up. Unlike stamping, photoetching gives a burr-free product resulting in cleaner more efficient screens with greater material integrity. These screens feature a tighter tolerance on hole sizes and greater dimensional stability than woven-wire mesh. This makes them ideal in applications requiring frequent cleaning or in devices with mechanical contact. Unlike woven-wire mesh screens, the fixed photoetched openings will not change through use. Typical applications for screens are in medical filters, laser-light filters, extruding screens, and particle separation and sizing. Other materials are available.
