A plastic element is press-fitted into a metal frame. A fully automated monitoring for this process is required. It has to be checked that no cracks in the plastic element emerge during the operation.
This is because any cracks in the plastic element can lead to fatigue fracture and functional failure of the component under normal load.
A complete visual inspection of the plastic element is not possible. As QASS’ structure-borne sound technology provides a view of what is going on inside the component even when it is not possible to look inside, it is applied to monitor the assembly procedure.
