Large weld - Import export

The ultrasonic actuators of the TWINLINE product line are used for solving weld tasks with a Herrmann Ultrasonic 20 kHz twin sonotrode. The finely tuned twin-stack is mounted on a carriage. The construction and design principle allows for large weld forces and high precision. This product line also provides a number of variants.

Optimal machine design for 20 kHz applications for which the joining process must be precisely performed by several sonotrodes in a single weld process. The rigid sonotrode support is realized by means of individual alignment modules and allows for accurate positioning even at large weld forces. Contrary to conventional designs, the weld stroke is performed by the anvil. During this stage, the plastic parts to be welded are moved against the stationary sonotrodes. Thus, it is possible to obtain machine cycle times of less than 10 seconds.
