Detecting surface defects

As well as the visual requirements, instrumentation panels also have to fulfill functional and security requirements. Often the passenger airbag has a predetermined breaking line which is generated using a laser. This »weak point« ensures the safe opening of the airbag at the predetermined breaking line. Sink marks may appear, which can be recognised under certain light conditions. In order to recognise these defects, surfaceCONTROL inspection systems are used which enable fast and objective evaluations to be made of the characteristics of any shape deviations, both on grained and smooth surfaces.
