Benefits of Photo etching machining include:
1. Low cost for tooling
All the tooling is created via computer-aided design( CAD) in a relatively short time frame with no time consuming mechanical processes involved. While tooling " wearing out" is unlikely using this photo etching process, replacement cost for tools are minimal.
2. Low cost modifications
The photochemical machining process allows the designer try different design variations at a minimum cost, since photo etching allows for short runs, cost effective improvements are relatively simple to implement.
3.Prototype to production
photochemical etching can be used to make one part or a million parts, with the exact same tooling used every time. This allows the engineer or the designer to develop their concept from prototype to pilot to production quickly and easily.
4. Metal properties unaffected
Photo etching carries the unique advantages of leaving the internal structure of the metal unchanged. The process does not affect the properties of the metal with regard to hardness, grain structure, or ductility.
5. Burr free
Some processes leave finishes parts with a burr which is detrimental to the functioning of the parts. The photochemical etchingprocess, however, produces burr free components, eliminating costly time-consuming de-burring.
6.Identification marks
Company logos, part numbers or other identifying marks can easily be photo etched into the surface of the material duringmanufacture at no extra cost.
7. Products with complexed shape
