Résumé : |
A new process allows individual droplets of PVC to be applied at high frequency to components that need to be sealed. The automated high-precision system reduces material use by up to 50 percent and cuts the amount of manual rework required byup to 40 percent. |
Note de contenu : |
- Dynamic automated sealant application
- Short reaction times for high-precision application
- Less material and less manual rework
- Fig. 1 : Here a lamp dome is being sealed with five thin material jets. Using the previous application system, the PVC seam was too thick at the turning points, which meant that manual reworking was needed to avoid leaks and brush out excess material
- Fig. 2 : The new technology applies individual droplets of PVC at high frequency via five material valves. The material valves can be individually controlled and the droplet size is variable, which allows for accurate application of the sealant and sharp contours
- Fig. 3 : Audi uses the process for precision sealing of seams on the Q3 and Q3 Sportback at its plant in Gyôr in Hungary |
