We also attach particular importance to finding the optimum solution to your application with our special machines standard machines, systems and components.
Ultrasonic welding can be found everywhere where thermoplastics, polymer-compatible plastics are used and where strict demands are made of the joining system. Depending on their polymer compatibility, thermoplastic materials, such as PP, PVC, PE, PET, ABS, composite materials, fabrics, fleeces or films are suitable for welding with ultrasound.
Compared with other welding processes, ultrasonic welding is ideal if rapid process times and good process reliability are demanded. Moreover, ultrasonic welding is characterised by the quality, strength and precise reproducibility of the welds.
Ultrasonic riveting is ideal for producing a positive connection between thermoplastics or with non-plastics. Whilst the cycle times of ultrasonic riveting are greater than for flat welding, several rivets can be simultaneously applied with one sonotrode. Just like ultrasonic welding, riveting with ultrasound is also very efficient and at the same time saves energy. The technology is used mainly where fusion joins are not possible, where metal parts are to be inserted in a plastic housing or where the join is subsequently invisible.
