SCHLEICH |Designed & Made in Germany.

We design and produce almost all components of our test equipment for you at our company site in Hemer in the Sauerland region.

Thanks to our computer-aided production control and our digital employee information system, we can guarantee maximum efficiency and process reliability along the entire production chain.

In our test equipment, advanced high-end processors perform your measuring tasks quickly, precisely and reliably. We also produce the required measurement and electronic boards ourselves using advanced in-line SMD assembly technology. We also manufacture a wide range of accessory components such as test covers, contactings, production lines, workpiece carriers with test piece holders or robot-grippers using our in-house own state-of-the-art CNC machinery.

This is how we ensure the consistently high quality of all SCHLEICH products.
