Ultrasonic welding
Plastics Packaging Nonwovens

Ultrasonic welding means joining without adhesives, screws or heat from an outside source. During this process, plastics are strategically melted by means of ultrasonic vibrations so that a cohesive or form-fit joint is produced. As economic production method with short cycle times, ultrasonic welding ensures a large degree of process control and repeatable quality results.

Ultrasonics can do "Industrie 4.0"

Understand more about “Industrie 4.0” when looking at the newly developed ultrasonic generator by Herrmann Ultraschall. The generator is the heart beat of the ultrasonic welding process answerable for repeatability and precision. Complex control algorithms and interfaces ensure an intelligent and sensible interaction with the production environment for perfect weld results.

Ultrasonic Welding Technology with Functional Integration

This trend cannot be overlooked: Companies who weld thermoplastic parts using ultrasonics are increasingly inquiring about the integration of additional upstream and downstream processes that are combined in the control system of one single ultrasonic welding machine.

Ultrasonic sealing system in Bosch flowwrapper

The use of patented ultrasonic sealing technology helps to achieve significant material and energy savings. The gentle ultrasonic sealing process allows the use of thinner and less expensive packaging films because no additional hot sealing layer is needed in the film. Further, ultrasonic sealing produces narrower seals, which reduces the amount of material needed.
