Photo etching, also known as chemical etching is a method to manufacture mechanical details from thin sheeet metals. As the manufacturing time is the same regardless of detail geometry, the etching process is very beneficial for complex details. The process is flexible and allows for freedom in the detail layout.
As opposed to punching, photo etching does not require any complicated and expensive tooling. As long as the manufacturing volume is not very large, it is in most cases more cost effective to chemically etch the detail. The cost for the photo tool is low and it is also relatively easy to make design changes.
Compared to laser cutting, photo etching has the advantage of no burr along the edge and the material is not subject to any thermal stress. For detailed geometries, the etching process is pre-eminent as the whole sheet is produced simultaneously and manufacturing time the same regardless of complexity.
Advantages of photo-etching:
Most etched mechanical details are produced by etching from both top and bottom side simultaneously. Can be combined with half-etching for logos and text markings and other features.
