 Photochemical
etching is an ideal process for grids, screens,
meshes, filters, separators and other perforated
metal applications.
The 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 leaves
the material free of burrs and induced mechanical or thermal stress or deformation.
Applications range from heavy gauge effluent
filtration to extremely fine thin-gauge
filters and diaphragms for liquids and gases.
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 applications. In many cases, chemical etching of metal meshes provide better value and performance than woven or punched products.
