Etching process in 3 dimensions

Precision and complexity characterise today’s medical devices, and this is certainly the case when looking at the manufacture of blades for medical applications. The photo tooling used in photo-chemical etching is easy and inexpensive to change, and so engineers have the design freedom to try multiple iterations in order to optimise and innovate ground-breaking geometries.

micrometal's Etching Group developed its photo-chemical etching technology to allow for the exact control of the etching process in 3 dimensions, which facilitates the creation of complex geometries for lancet or scalpel blades in industrial quantities. We also make blades for consumer products such as shavers, where the cutting capacity of the blade is optimised through the use of our photo-chemical etching process. Photo-chemical etching also benefits from producing burr- and stress-free parts, and innovative features can be included while achieving exacting tolerances that cannot be matched by alternative traditional metal fabrication processes.
