Precise cutting with ultrasonic technology by SONOTRONIC

Ultrasonic technology by SONOTRONIC enables cutting and separation processes for various products in the food industry to be automated. The units and systems can be easily integrated into existing machine concepts. Special tools (sonotrodes), which are made to oscillate by ultrasound, cut the particular product into pieces. As a result of the oscillation and the optional coating, the nonstick characteristics of the cutting sonotrodes are especially good. Cutting with ultrasound makes it possible to cut both very soft and very hard products efficiently.

Ultrasonic cutting sonotrodes:The sonotrodes conduct the ultrasonic oscillation into the workpiece and are individually tailored to size according to the application. Shape and contour can be adapted to your requirements. The development and production is based on the finite element method (FEM), which ensures optimum ultrasonic processing of the applications. SONOTRONIC offers cutting sonotrodes with a blade length of up to 750 mm and a cutting height of up to 170 mm.

Continuous ultrasonic cutting and sealing

The ultrasonic roll seam units from SONOTRONIC are suitable not only for continuous sealing but also for the simultaneous cutting and sealing of synthetic textiles.

Continuous sealing seams with high design flexibility

In ultrasonic roll seam sealing, continuous sealing seams are produced by the disc-shaped sonotrode without seam interruptions, for which purpose the roll seam sonotrode has a titanium mounting on both sides. At the same time the design of the anvil wheels with different contours and widths allows flexibility in seam design.

Simultaneous cutting and sealing (Cut & Seal)

A further application of the innovative ultrasonic roll seam technology from SONOTRONIC is the simultaneous cutting and sealing of thermoplastic textiles with extremely wear-resistant steel sonotrodes. This produces not only fixed seams but also minimal seam projections. During ultrasonic edge cutting the edges are already sealed so that they cannot fray.

ultrasonic punching

Possible applications In the textile industry ultrasonic roll seam units replace conventional sewing machines. Continuous sealing seams and seams with free geometries can be produced. Fabrics from thermoplastic synthetic fibres are then no longer sewn with one thread but are sealed ultrasonically, and because of this no holes are made in the fabric by needle stitches and there is no subsequent taping. Besides their use at manual workstations, ultrasonic roll seam systems can also be integrated in existing machines.

Ultrasonic sealing without heat loading of the filling material

An ever expanding application for the continuous ultrasonic sealing method from SONOTRONIC lies in packaging technology.

Applications

Here ultrasonic roll seam technology is applied mainly in horizontal and vertical tubular bag machines. Bags with four sealed edges can also be produced by ultrasonic roll seam sealing.

New possibilities in the choice of film

In addition, unlike other thermal processes, ultrasonic technology makes it possible to use monofilms, since no heat-insensitive outer layer needs to be laminated onto the film. Furthermore, even very thin polymer films (15 μm) can be sealed in high quality with the continuous ultrasonic process, which has not been possible satisfactorily with other thermal sealing systems so far.

Economic process Both the roll seam sonotrode and the anvil are driven in this process so that there is neither slip nor wave formation in the film. No relative movement is generated between the sealing wheel and film by the double drive either.
