Custom Photo-Etched Screens and Filters

Tech-Etch photo etches custom screens, filters and filter supports for many diverse uses, including hydraulic valve screens, extruding screens, particle separation, and sizing. Photo etching enables designers to specify a straight hole or a tapered hole, which facilitates liquid filtration and back flow cleaning. Hole sizes range from .003 in. and up. Unlike stamping, photo etching yields a burr-free product, resulting in cleaner more efficient screens with greater material integrity. Photo-etched screens feature a tighter tolerance on hole sizes and greater dimensional stability than woven wire mesh, making them ideal in applications requiring frequent cleaning or in devices where there is mechanical contact. Unlike woven wire mesh screens, the fixed photo etched openings will not change through use. These tight tolerance screens are primarily produced from stainless steel, but other materials, including polyimide, are available.
