Wet-out tests are used to aid in the validation of the design and manufacturing process of a tape-attached trim component in the assembly process. Wet-out testing confirms sufficient contact of the tape to the vehicle. Key elements for successful wet-out include part match to vehicle, roller angle, location, and pressure.
The recommended minimum wet-out is 80%. Applications demonstrating less than 80% wet-out are questionable and are candidates for further process and/or design improvements. Any single area without wet-out shall represent no more than 15% of the total tape surface area. Examples of wet-out test results are included below.
