Photochemical Machining Processes
Photochemical Machining allows for the manufacture of precision thin metal parts that are both high-quality and low-cost. PCM is a process that begins with your initial drawing or blueprint. From the blueprint a precision artwork or "tooling" is made up. This "tooling" or image of the part is then transferred to thin metal sheets as a coating of photo-sensitive resist that acts as a mask defining the part. The metal surrounding the part is chemically removed utilizing a power-spray etching machine.Some of the advantages of PCM are: the material is not subjected to forces which might cause distortion or stress, raised burrs do not result from this process, and virtually any configuration can be achieved. In addition, Most common metals can be photo chemically machined. There is a "non-recurring one-time tooling charge" because PCM "tooling" or artwork can be used repeatedly and is essentially non-destructible. Please check our FAQ Page for more information regarding tooling costs.
Common parts that are manufactured through PCM include, but are not limited to, electrical contacts, heat sinks, flat and formed springs, RF shields, and precision shims.
