Welding dissimilar thermoplastic materials according to their polymer compatibility, such as PP, PVC, PE, PET, ABS, composites, tissues, fleece or films. Ultrasonic plastic welding is suitable for virtually all thermoplastics. When planning welds between semi-crystalline plastic work pieces, it is important to remember that the welding behavior of these plastics differs considerably from that of amorphous plastics. The longitudinal and torsional methods produce very different welds. In addition to the proven longitudinal welding processes we offer exclusively offer the torsional ultrasonic welding SONIQTWIST®, which is characterized by minimal component stress.

Ultrasonic sealing meets all the requirements for processing coated carton materials. The special advantage here is that the ultrasonic energy is directly transferred through the most diverse laminate constructions to the (inner) sealing layer. SONIQTWIST® is the new ultrasonic sealing technology for e. g. containers and cans. The Torsional-method developed and patented by us redefines ultrasonic sealing and welding.

The vibration welding process is ideally suited for applications on large components, parts which have a stepped or contoured profile, and parts which have hard-to-reach areas. The process is used extensively within the automotive sector to join and assemble large parts such as instrument panels, bumpers, spoilers and underbody panels plus smaller items such as fluid reservoirs, tanks, and light clusters where a hermetic seal is required. Vibration Welding is also suitable for use in other manufacturing sectors such as domestic appliances and durable household products such as lawn mowers and other technical plastics applications.

A key characteristic of this process is its ability to weld and join a comprehensive range of plastics, either from the same material group or as a combination of different material types. Semi-crystalline, reinforced, non-reinforced and polyamides are among the wide range of materials which are suitable for the process. The full material list can be found HERE.
