Welding of materials within milliseconds, according to type
The feasibility and joining properties of bioplastics is currently under research
Thanks to their versatile use, their robustness and safety, plastics are highly valuable materials. But it is important to use plastic products sensibly and to recycle them whenever possible. This is best and most easily done if plastic components are joined without the addition of glues.
Sustainable processing thanks to ultrasonics
Ultrasonic welding helps in processing of pure plastics without additives. Ultrasonics introduces thermal energy into the insides of the joint area of plastic components by means of friction. The components are welded, formed, staked, crimped, or embedded without the addition of other substances. This means that no different materials are combined for the products and recycling is easier. And what is more, ultrasonic welding itself is a sustainable process. For the machines are ready for operation without any heat-up times and joining of components takes place within a few milliseconds. This saves energy. Ultrasonics is used for thermoplastic materials and nonferrous metals, as well as with recyclates, paper compounds, or bioplastics. As a leading specialist, Herrmann has perfected processes for applications in the fields of automotive, packaging, hygiene, and medical engineering, electronics, battery engineering, and consumer goods.
