Component simulation, strength calculations, filling studies and FMEA. 

Series production control

Optical and tactile measurements in in-house measuring rooms.

Annual requalification

Regular inspection of serial parts, supplier audits and repeat audits.

Our team

Wherever mobility development takes us, we will always respond to our customers‘ requirements.
