The SLIMDESIGN design team specializes in Design and Mechanical Engineering. For complex projects selected partners with the same flexibility and drive for perfection. Depending on the project’s requirements we can add them to the team. This way we stay flexible and can make sure we work with the best experts in their field.

Development Partners

For complex projects we have selected partners that have similar flexibility and drive for perfection. We assemble a core team that develop all aspects (design, ME and EE) simultaneously and remain with the project from start to finish. In this way there is fluid communication, no loss of information and late changes are easier to handle.

Electronic Engineering Team
