Reliable joining technologies

For the processing of thermoplastic materials such as PP, PC, PA, ABS, PMMA or ASA as well as blends of PP-EPDM, PC/ABS, PC/PBT or composite materials, for example, textile/PUR, slush/PUR/ABS, we rely on innovative ultrasonic technology. For special tasks, infrared, hot plate and hot air technology are also used.

Ultrasonic technology is characterized by excellent properties such as short process times, low energy consumption and high reproducibility of welding and punching results. In addition, ultrasonic can also be used to efficiently and extremely gently process particularly high-quality plastics, such as those frequently found in the automotive industry.

Ultrasonic punching - can be combined with other processes

After ultrasonic welding machines have proven themselves for various applications in the automotive industry, SONOTRONIC has projected the advantages of ultrasonic to punching as well, thus creating new paths. With simultaneous flexibility, the highest possible punching quality is achieved with the patented process using ultrasonic technology. 

Depending on the requirements, we combine processes such as punching, riveting, embossing, gluing, and screwing in one system or develop flexible production lines for fully comprehensive assembly, which are freely configurable due to their modular design.
