About chemical etching technology:

1.Photochemical etching is an ideal process for metal grids, screens, meshes, filters, separators, microfilters, grilles, lighting diffusers and other perforated metal applications.

2.The photo etching process produces perforated metal parts with 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.”

3.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.
