Operations management

Flexible, fast and precise – production of the highest quality

With welding, machining, assembly or any other manufacturing process – our plant manager, Mr Humpert, and his teams in work preparation, purchasing and production always find the best solution for technical implementation.
Besides our skilled staff, the key to our mutual success lies in our modern machine park, digitalisation through CAM, efficient ERP system and PDM/DMS for data management.

Accounting and administration




Our company was founded on 01/07/1938 by Hans Eilhauer at the location in Langenhagen. After the company’s successful development, the management role was handed over to his son, Hans-Michael Eilhauer, in 1978. Through steady investment and continuous development, he has successfully managed the family business. The success, then and now, can be attributed to our management as well as our long-standing experienced employees and mutual trust.
