Medical Technology

Medical engineering, zero tolerance

Medical technology is subject to extremely strict regulations and specifications for good reason. The strictest product and safety requirements must be met as early as the development phase and have to be verified.

In our capacity as an experienced partner of medical technology companies (manufacturers, importers and dealers) we develop parts, assemblies and systems. We support you with our expertise in every phase from concept and development through to the manufacturing processes. Benefit in particular from our standardised design solutions for CE marking your products right through to initial sample testing.
