SinoGuide’s etched filter screens are made through advanced photo or chemical etching technology, which yield a burr-free articles.
Etched Filter Screens are manufactured by SinoGuide using photo etching or photo chemical milling technology. Unlike stamping, photoetching yields a burr-free product resulting in cleaner more efficient screens with greater material integrity. These superior quality screens feature tighter tolerance hole sizes and greater dimensional stability than woven wire mesh, which 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. Photoetching also enables designers to specify a conical hole, which facilitates liquid filtration and back flow cleaning.
Typical applications of Etched Filter 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.
SinoGuide offers a standard line of screens with holes in a 60° or 90° pattern that are available with a usable perforated area of at least 18” x 21” as shown on the chart below. Other sizes and custom shapes are also available.
Photo Chemical Etching Filters
SinoGuide manufactures bespoke, high performance single piece metal meshes for a myriad of uses, including filters, sieves, grilles and screens. In addition to conventional flat metal meshes, SinoGuide can also manufacture precision column filters by laminating pre-machined metal shims to the required height.
Holes offered in conical profiles as illustrated by the sample and cross section profile below.
Holes offered in straight profiles as illustrated by the sample and cross section profile below.
