From Tech-Etch, Inc.
Photo etching, also called chemical milling, photochemical machining
and chemical machining, offers many advantages for manufacturing
thin metal or polymer film medical parts, including improved accuracy,
low-cost tooling, inexpensive prototyping, burr free parts, and speed of
Specialty materials such as tungsten, molybdenum, nltlnol, tItanIum,
elglloy and polylmlde have characteristics that are attractive to the
medical industry as components for medical devices such as heart
valves, intraocular lenses, pacemaker batteries, surgical tools and
catheters. In addition to these specialty materials, photo etching is
highly suitable for other metals including beryllium copper, stainless
steels, niobium, silver, brass and spring steels.
