Custom Photo Etched Screens & Filters

Etched Screens and Filters

Plymouth, MA....Tech-Etch photo etches custom screens, filters and filter supports for many diverse uses, including medical devices, hydraulic valve screens, laser light filters, fuel filters, extruding screens, liquid filtration, 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" 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. Tech-Etch also offers a standard line of MicroEtch® screens with holes in a 60° or 90° pattern that are available with a maximum guaranteed perforated area of 18" x 21".
