For the assembly of plastic parts which differ in size and condition and would therefore not be suitable for standard machines, we recommend the use of special equipment  with several ultrasonic units for ultrasonic welding and processing methods..

Multi-head Systems

These machines can also be used to accomplish complex tasks, e.g. the combination of different welding techniques, like spin welding and hotplate welding and for numerous automated processes.

Flexible KLN piping technique

for flexible settings of the process position. The pneumatic actuators are preferably fixed within a flexible piping system. This method allows an unrestricted number of settings of the welding position, providing a cost-effecitve possibility to incorporate changes which occur during the construction phase

This includes techniques for adding clips and other procedures like printing and embossing as well as barcode or automatic assembly systems being part of quality assurance and complete documentation.

Tools

For every welding task, we offer state-of-the-art tooling designs taking into consideration sensitive visible surfaces varnish or leather coated, shagreened or foam lined. Manufacturing and optimization are in accordance with CAD da

Exchange unit technique

The exchange unit allows a tool exchange for different parts without changing the basic machine. The installation of sonotrodes after the change is not necessary.

At KLN, the manufacturing of transducers is subject to a most elaborate procedure, e.g. lapping on the highest quality level and an assembling method of the components which has been developed by KLN for especially this purpose. In this regard, our clients can profit from our 60- year experience in the field of transducers technology.

All KLN ultrasonic units are fitted with integrated titanium boosters and safety housings, and have always a high starting amplitude of approx 10 µ. This technique gives a maximum protection for the piezo-ceramic converters and  simultaneously reduces the heating up of the sonotrodes, as the desired operating amplitude is usually achieved with low sonotrode transformation.

Due to their linear precision railings, these actuators have a high degree of precision. The actuator is additionally combined with cylinder switches for the parking position, the ultrasound impetus and melt control for travel switch, as well as for other special techniques such as tandem cylinder systems and encoder position sensors.
