Microetch ScreensExtremely Fine Stainless Steel MicroEtch® Screens

Plymouth, MA....Fine MicroEtch® Screens from Stainless Steel are manufactured by Tech-Etch using photoetching technology. Photoetching 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, photoetching yields a burr-free product resulting in cleaner more efficient screens with greater material integrity. These superior quality 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 where there is mechanical contact. Unlike woven wire mesh screens, the fixed photoetched openings will not change through use. Typical applications of MicroEtch® Screens are filters used in the medical market, hydraulic valve screens, fuel filters, laser light filters, extruding screens, as well as particle separation and sizing. These tight tolerance screens are primarily produced from Stainless Steel, but other materials are available. Tech-Etch, Inc. offers a standard line of screens with holes in a 60° or 90° pattern that are available with a maximum guaranteed perforated area of 18” x 21”. Other sizes and custom shapes are also available.
