Manufacturing - Chemical Machining

Chemical Machining is the clean removal of metal from pre described areas without altering the integrity or properties of the metal by means of a photochemical process. This process is primarily used in creating small thin metal parts of complex design with no burns or stresses to the parts.

The process starts by cleaning the dirt and oils from the metal. A photoresist is applied and baked to assure an even application. The artwork is then placed over the prepared sheet of metal and exposed to ultra-violet light, resulting in the desired resolution and etch specs. The artwork is removed and the resist is ready to be developed or removed. At this point the metal is ready to be etched by submerging the sheet in a chemical solution that dissolves all the material that is not integral to the part. After the etching is completed the resist is removed and the metal parts are cleaned, inspected and packaged.
