Quick joining process for the lid components of resealable drinks cans
Resealable drinks cans are convenient, especially when driving and walking, but also for many other activities. You do not have to drink the entire can in one go, the drink retains its taste and fizz and it is not possible for insects or dirt to get into the can. Ultrasonic welding technology has proven itself to be an effective and economical means of joining the lid components of resealable drinks cans. Xolution GmbH, a company based in Munich, has developed an ingenious resealable lid mechanism for drinks cans. The innovative XO relock system is suitable for all can sizes.
The ultrasonic equipment consists of four components that can be easily integrated into equipment manufacturers' systems: the ultrasonic generator that generates the high-frequency electrical vibrations, the converter that converts them into mechanical oscillations, a booster for amplification and the sonotrode. The latter introduces the mechanical oscillations into the workpiece. Converter, booster and sonotrode have a fixed mechanical coupling and their acoustic resonances are tuned to one another. The generator has a key function, as it not only generates the high-frequency electrical vibrations, but also provides the connection to the higher-level automation technology in the context of Industry 4.0. State-of-the-art bus systems enable welding parameters to be adapted and results to be read out in real time. Furthermore, system costs can be optimised because it is possible to switch between different resonance units. The external setpoint defaults for amplitude, time, energy and Pmax, as well as soft start for large sonotrodes and frequency autotuning, are just some of the additional features that provide maximum process stability. Xolution GmbH has therefore found the ideal joining technology for manufacturing can lids with the XO relock system.
