Photochemical etching is an ideal process for metal grids, screens, meshes, filters, separators, microfilters, grilles, lighting diffusers and other perforated metal applications.
The photo etching process produces consistent, burr-free holes as small as .004” in .002” thick material. As a general rule, minimum hole size is 110% of the thickness of the material, e.g. on .010” material, the smallest hole would be .011.”
Unlike mechanical perforating methods such as punching, stamping or laser cutting, photochemical machining of metal leaves the material free of burrs and induced mechanical or thermal stress or deformation.
Rechargeable nickel metal hydride (NiMH) batteries are constructed using nickel as the positive node. The nickel electrodes, or cathodes, are grids or screens of varying configurations that are readily produced by photo etching. NiMH batteries are rapidly replacing NiCad because they do not contain toxic cadmium and offer better life cycle performance.
Very fine features can be created in stainless, moly and other alloys to allow pattern deposition for a number of electronics applications.
Applications range from heavy gauge metal effluent filtration to extremely fine thin-gauge filters and diaphragms for liquids and gasses in a variety of alloys including steel, copper, aluminum, nickel and molybdenum.
Industrial, Architectural, Decorative
Metal meshes can be photo etched in a wide variety of alloys including steel, nickel, copper, brass, aluminum and more. Holes can be made in a variety of shapes and sizes at no additional cost in tooling.
Photo etched meshes, grids, filters and screens are used in many types of industrial, decorative and architectural applications. In many cases, chemical etching of metal meshes, grids, screens and filters provide better value and performance than woven or punched products.
