Measuring coating thickness on application

摘要

A non-contact sensing solution, which can measure coating thickness as it is being applied, has helped speed up production processes and reduce scrap levels in the automotive industry. In the automotive industry, paint coatings are normally sprayed in a heated mould, using robot-guided nozzles. This process requires tight tolerances, particularly with safety-critical parts such as airbag cladding. It is preferable to measure the thickness of the paint skin during the spraying process itself, rather than waiting for the paint to dry.
