Photochemical etching is, essentially a “2D” process. We work with flat panels of thin gauge metals to produce parts from the very simple to very complex.
We receive many inquiries from people who are looking for a chemical etching process that can be used on three-dimensional parts.
Electro-chemical etching is a process that is required on many defense and medical parts. T.U.S. Technologies, Inc., 46 Gifford Street, New Bedford, MA 02744.
