Description:


The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.

Applications:


Laminating of nonwoven materials using ultrasonics

The general principle of ultrasonic welding can also be applied to nonwoven materials. The thermoplastic fibers are activated by mechanical vibrations thus melting and bonding in pre-defined patterns. A weld tool, referred to as Sonotrode, transmits the vibration into the nonwoven material. In industrial applications, ultrasonic frequencies between 20 and 35 kHz are common, with amplitudes (tool travel distances) of 10 µm to 50 µm. Processing of nonwoven materials is often performed in continuous processes at high web speed. By application of rotary tools, it is possible to achieve processing speeds of up to 800 meters/minute. A specifically engraved drum is used as welding, embossing, or cutting anvil. The contour of the anvil drum focuses the energy and precisely defines the weld spots required for the respective product.

Competitive Advantage:


Laminating of various layers

Embossing

Separating and seaming of edges

Perforating of web material

With welding of web material it is important to keep the distance between the material and the sonotrode consistent. Only then good and uniform results are possible. To ensure this, we offer a patented machine controller. It controls the travel movement of the actuator or the sonotrode via a stepper motor with very high position resolution and thus achieves that the thermally caused change at the ultrasonic tool is compensated and the force between the sonotrode and the anvil drum with contour is always kept consistent.
