Photo Chemical Machining (PCM)

The photo-etching process lends itself to such applications allowing for a series of complex designs, mesh patterns, and logos to be fabricated simultaneously, in a single machining operation. The process also boasts burr-free openings to micron tolerances and high definition surface engraving. The ability to change grille patterns with minimal tooling costs is a further benefit during the design and development phase.

Photochemical Machining Overview

Chemical Etching Advantages

Very simply, chemical etching is a process used to remove material (metal) by way of masking an area with a protectant (photo resist) and then submerging the material into an etchant (acid) to remove the material that has not been protected by the photo resist - Complex designs are simple to produce
