Etching perforated metal products are ideal for making metal meshes, screens, grids and filters with precision and small holes. The minimum diameter of the hole size can be as small as 110% of metal thickness and the minimum ligature between holes can be equal to metal thickness.

Photo etched stainless steel filter for very small holes
Stainless steel filter processed by photo etching will not deform

Photo etching is used to produce consistent small holes for filtering or other purposes. In contrast to mechanical perforating processes such as punching, stamping or laser cutting, photo etching leaves no burrs and causes stress concentration and deformation.
