Fine MicroEtch screens for filtering are manufactured using photoetching technology. Unlike stamping, photoetching yields a burr-free product, resulting in cleaner, more efficient screens with greater material integrity. They are ideal for use as filters in the medical market. These tight tolerance screens are primarily produced from stainless steel, but other materials such as polyimide are available. Hole sizes range from 0.003 inches and up. The standard line has holes in a 60° or 90° pattern that are available with a maximum guaranteed perforated area of 18 inches× 21 inches. Other sizes and custom shapes are available.
