what is photo etching?
Chemical etching (photo etching) is a photo-lithographic process whereby a phototool is used to block UV light from exposing the area of a sheet of metal which has first been cleaned and laminated with photoresist. The sheet is developed which washes away the unexposed photoresist leaving a very precise mask of hardened photoresist behind. This patterned sheet is then exposed to concentrated etchants which very precisely dissolve any exposed material.
 
Photo Etching or photochemical machining is a fast and cost-effective alternative to traditional tooling methods and can be one of the most inexpensive processes for manufacturing short-run metal parts.
In the photo etching process, film is generally used to expose metal to light and is not subject to the same type of wear as traditional stamping and punching dies.
Since the cost of tooling is much less expensive, photo chemical etching is a more cost–effective method for producing short-run jobs such as prototypes.
Unlike many traditional production methods, most photo etching tools can be produced in hours-not days.
