Welded parts - Import export

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.

Shuttle table machines are characterized by an operating area that is separated from the loading station. The plastic parts to be welded can thus be optimally loaded into the equipment. Thanks to good accessibility, assembly and loading tasks can be easily performed. Can optionally be designed with one or more work stations. Approach of several operating positions is performed by means of a freely programmable linear drive. In this way, weld tasks can be divided into individual process steps. Tool change systems: optionally available.

The core of this ultrasonic welding machine is the patented pneumatic HMC drive concept. It combines the benefits of pneumatics with the dynamics of an electrical drive and allows for selection of any optional start point for the weld process. The SoftTouch mode protects the sensitive joining area of the plastic parts to be welded during contact of the sonotrode.

With the help of the MULTICELL concept, small multi-head applications can be easily implemented. In general, the plastic parts to be welded are loaded directly below the sonotrodes. A shuttle table can be optionally integrated for improved handling. This modular concept is particularly suitable for 20 kHz applications with sound insulation and can be customized by installation of a large number of accessory options. The compact make-up and high degree of mobility allow for universal application in manufacturing.
