Sonotronic Nagel: Ultrasonic riveting of washing machine doors

摘要

The main difference between ultrasonic welding and ultrasonic riveting relates to the fact that, during riveting, the melt is deformed and just one of the two joining members is plastified. This makes it possible, even without any direct polymer compatibility, to join all thermoplastics not only with each other but also with non-plastics. This results in riveted joints with hardly any gaps or clearances. The technology is mainly utilised wherever large-area welds are not possible, e.g. on a washing machine door.
