The complete ultrasonic welding system is composed of active and passive components. The active components generate the vibrations, transfer them, and apply them into the weld parts The passive components absorb the resulting forces, maintain the parts in position, and particularly support the weld joint.



Ultrasonic generator
Weld tool referred to as sonotrode



Fixture or anvil


The converter, booster, and sonotrode are combined to form what is referred to as stack.

The fully digital ultrasonic generator uses the supply voltage to generate high voltage in the respectively required ultrasonic frequency. All data relevant for the weld process are precisely measured and analyzed. The generator protects the vibrating system from overload, keeps the amplitude (tool movement) at a constant level, and compensates for the changing vibrating behavior of different weld tools.

The converter represents the interface between the electrical and the mechanical area. Utilizing the inverse piezoelectric effect, it converts the electrical oscillation to mechanical longitudinal vibration and transfers it to the booster or the sonotrode.

The amplitude transformer, often referred to as booster, increases or reduces the amplitude coming from the converter. Being suspended at nodal plain, the booster can also be used for vibration-free support of the stack in the ultrasonic welding machine and for transmission of forces.

The sonotrode being the actual active weld tool, transmits the mechanical vibrations into the part; i.e. it launches the ultrasonic vibration. Depending on its design geometry, the sonotrode can either increase or reduce the amplitude.

The stack is always adapted and optimized with regard to the plastic material and the geometry of the part’s contact.



Ultrasonic welding
Assembly by energy applicator. Mainly reserved for amorphous thermoplastics. Ultrasound welding is done very quickly (less than 1 second), without adding material.


Ultrasonic spot welding
Ultrasound spot welding is particularly recommended for thermoformed parts without an assembly profile, or for parts whose geometry and actual conditions exclude the possibility of standard welding operations.


Continuous ultrasonic welding
Applied to high speed processes, continuous ultrasound welding is a solution for the high flow rates in the fields of packaging and non-woven textiles.


Ultrasonic riveting assembly
The main advantage of this process is that it allows to assemble parts of different types of plastic.


This technique encloses a part within a completely different material, by deformation of the material.


The penetration of metal inserts by ultrasound makes it possible to avoid the stresses due to overmoulding, to increase the injection rates and to simplify the production of injection moulds.
