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.
Areas of Application:
Spotwelding, rivet and crimping connections on e.g. inside linings, instrument panels, seats and bumpers ++ more details
This method is a type of high-frequency friction welding. The vibrations are applied tangentially. ++ more details
Boxes (for beverages)
Ultrasonic sealing meets all the requirements for processing coated carton materials. ++ more details
As in metal working, moulded parts made of plastic can also be flanged. ++ more details
Embedding of Metal Parts
Threaded inserts, grub screws orother metal parts can be ultrasonically embedded in thermoplastics. ++ more details
Cups, bowls, trays and blisters
The opening behaviour of packagings plays an increasingly important role in the customer’s product acceptance. ++ more details
The function of the energy director is to initiate rapidly plastisation of the joining surface by the concentration of energy. ++ more details
Ultrasonic spotwelding is used predominantly where for instance flat mouldings without weld preparation (ED) have to be welded. ++ more details
Pouches with addtl. Functions
Great variety of additional possibilities to realize special features on pouches: spouts, valves, header, etc. ++ more details
