We specially developed the cantilevered ultrasonic roll seam module for the seamless welding of films and fleeces. The non-slip parallel drive by sonotrode and anvil wheel enables particle-free welding to be achieved on films up to a thickness of approx. 15 μm.  Fleeces can also be welded with the roll seam module. Depending on material and film thickness, welding speeds of up to approx. 80 m/min are possible.

At Fakuma, we presented to the public for the first time, our new machine concept for punching bumpers. In order to meet the increasing demands of our customers, SONOTRONIC as the pioneer in ultrasonic punching, last year developed a space and cost-saving machine concept. The special feature of the module punching concept lies in the fact that punching, cone punching and joining are combined in one process.  Parking sensor holders can optionally be glued into place or welded on by ultrasound.
The new concept is extended by an intelligent holding system, which allows the workpiece to be removed or inserted within one position. The visitors to the trade fair were particularly impressed by the fact that the new machine concept not only cut cycle times and capital investment costs, but also, above all, reduced the size of the special machines by up to 50%.

To summarize, the new concept has the following advantages over conventional punching machine concepts:

• Improved overall efficiency
• Approx. 50% reduction in floor space
• Up to 40% cycle time reduction
• Overall costs reduced by up to 20%
• Identical punching and welding generators

We are also looking forward to welcoming you to our next stand again in Hall A4 at the next Fakuma. In the meantime we will be happy to give you any information and advise you on your individual solutions in the field of ultrasonic plastics processing.
