Key service and product areas

Mechanical Engineering

In the mechanical engineering sector, we offer a wide range of services relating to analysis, design, development and integration of drive units, transmissions, actuators and housings.


Mechatronic systems are found in all vehicles and form the basis of future-proof mobility concepts. They are also becoming increasingly important outside the automotive industry. However, whether in electric vehicles or collaborative robots (cobots), the seamless interaction between mechanics and electronics is always essential. And that is the point at which we take over.

The mechanical integration of electronics

Our extensive expertise in mechanical development makes us the ideal partner for mechatronic development projects. Electronic systems and their mechanical components are increasingly subjected to demanding requirements in terms of tightness, vibration endurance, thermal stability, etc. When motion becomes a factor, we develop your mechanical subsystem according to your special application.

Mechanical design
High performance drives play a decisive role in e-mobility and in modern industry.

Drive systems

High performance drives play a decisive role in e-mobility and in modern industry. The mechanical design of individual drive components and their interaction is challenging due to high power density, increasing speeds, maximum precision and the need for cost-effective manufacturability. Using our expertise in transmission, actuator and housing development, we provide the ideal solution for every application.

Mechanics, integration and simulation – we provide comprehensive solutions, as turn key solution

Given the prevailing high time and cost pressures, coupled with the increasing complexity of development, it is important to make the most of any potential for optimization, such as recruiting a partner for all your development work (by relying on one partner for all development tasks). As specialist in mechanics within the field of mechatronics, we possess the essential interdisciplinary expertise across multiple phases. Our interdisciplinary project teams enable us to efficiently address additional simulation and integration tasks in mechanical developments.

If you have any questions about our range of services in mechanical development, integration or simulation, please do not hesitate to contact us.
