Needles made by photo chemical etching

Medical devices are being made today requiring greater precision and increased complexity. The photo-chemical etching process is used for the manufacture of a variety of needles for medical applications. The photo tooling used in PCE can be changed cost-effectively, and so engineers have the design freedom to try multiple iterations in order to optimise and innovate ground-breaking geometries.

micrometal developed its photo-chemical etching technology to allow for the exact control of the etching process in 3 dimensions. In addition, the fact that the process produces burr- and stress-free parts means that it is ideally suited to the production of micro needles, which can also be manufactured with innovative tip features and excellent tolerance control.

Advantages at a glance

  • Multiple features in one part at no extra cost
  • Can be applied to tinanium
  • Burr free, stress free, clean and flat parts
  • Cost-effective tool production/design iterations
  • Realization of complex designs (channel structures)

Our standards are industry leading

We operate in a world characterized by the tightest tolerances (hundredths of a millimeter), the finest structures, the thinnest metals, and the most complex geometries. We etch customized metal components to the tightest tolerances in large-scale industrial production volumes.

Our mission is to reach the highest customer satisfaction through excellent quality. In order to guarantee this to our customers, our processes are constantly monitored and further developed through strict quality controls. We are certified according to ISO 9001, IATF 16949, and ISO 14001.
