Reference continuous welding with ultrasound
Production of roof underlays
Productivity, flexibility, and cost efficiency
Roof underlays are produced from various layers of material, which are bonded to one another as web materials and produced to customer specifications. Laminating with ultrasound is a quality-critical process for reproducible quality.
“Ultrasonic technology is used for a very wide range of applications and materials and suitable for continuous operation.”
FASTER, MORE FLEXIBLE, AND ENERGY-SAVING LAMINATION WITH ULTRASOUND
Ultrasonic welding offers significant benefits. First of all, it renders the heat-up times of the rollers that would otherwise be required for thermal processes a thing of the past. This not only saves energy, but also allows faster production.
In comparison with calendering, where radiant heat is applied over the entire surface, the web that is welded with ultrasound is also more flexible and softer, as well as free from deformations. There is also no risk of overheating. Since no adhesive is used, there are also no production downtime for the necessary cleaning of the rollers.
