Electrical Motion Ultrasonic Welding Machine

Particularly Accurate Sonotrode Control

The Electrical Motion ultrasonic welding machine (working frequency 20 kHz) from Rinco Ultrasonics, Romanshorn, Switzerland, meets the demanding requirements for tight tolerances, traceability and hygiene which are typical of medical technology. Its electrical drive and control by means of an ultrasonic generator with built-in industrial PC ensure particularly accurate sonotrode control, while welding force and rate are also accurately adjustable. This results in consistency and reproducibility of the welding, punching, cutting and sealing operations carried out on thermoplastic mouldings and films, nonwovens and synthetic textiles.

Thanks to its electrical drive, the Electrical Motion's welding force, rate and speed are very much more accurately controllable than on a conventional, pneumatically driven machine. Distance mode, for instance, permits positioning with an accuracy of 0.01 mm. The defined welding parameter data records and welding results can be exported from the machine's internal storage to an external data storage medium to enable compliance with the medical technology sector's audit and documentation requirements. In addition, a non-erasable audit trail records all events, for example maintenance operations and changes to parameters, for quality improvement and traceability purposes. Different hierarchical levels of authorization can be set, so ensuring that only authorised persons can change parameters or acknowledge events. The Electrical Motion has ISO Class 6 certification for clean room manufacture.

The machine's electrical drive also means that the sonotrode's starting position can be freely selected. As a result, unlike with a pneumatic drive, the sonotrode does not have to be returned to zero position for each welding cycle. Depending on the geometry of the object being welded, this can result in distinctly shorter cycle times. The integrated quick-change system means that tools can be swapped within a few minutes, so minimizing downtime. The Electrical Motion can also be installed for remote access service from Rinco headquarters.
