Cutting sonotrodes

Sonotrodes for high-strength materials

Sonotrodes are ultrasonic welding tools that are made to resonate when high-frequency mechanical oscillations are introduced. Sonotrodes are designed based on the Finite Element Method (FEM), and therefore guarantee optimum oscillation behaviour and long service life in all cases. The advantage of these sonotrodes is that the booster is already integrated and it does not need to be ordered. Boosters are used to increase or decrease the amplitude.

Coffee capsule application

Ultrasonic sealing is used in a wide variety of capsule and teabag applications.

Telsonic has developed a wide variety of tools to meet the high demands of the packaging industry, which can be quickly and easily integrated into automated systems.

The increasing sales volume of coffee capsules has led to increased demands on the sealing process. Ultrasonic sealing is a fast and highly economical process with the filters being punched and sealed in one step. Stable, repeatable quality and good process control are just some of the benefits of this system.

A high quality seal is achieved with Telsonic sealing units as the product residue is displaced from the seam, guaranteeing protection of the content and durability of the product.

Product category: Screening machines, classifiers, dedusting systems for plastic pellets


The requirements in the industrial screening process have become more complex, the powders finer, the throughput times shorter and the selectivity narrower. Equipment manufacturers are increasingly reaching their limitations under the high technical requirements. 

Ultrasonic methods offer solutions. Ultrasonic systems stimulate the finest screen fabric, increase throughput rates and improve, thanks to the permanent cleaning of the screen, the degree of selectivity of the screened product. 

Ultrasonic components integrated into screening systems prevent the screen fabric from becoming clogged. The throughput is increased and the selectivity of the screened product is improved. The optimised resonance system from Telsonic delivers the maximum for the lowest expenditure. Even the finest screen fabric fulfils the requirements.

Backed by some 20 years' experience, Telsonic is as a specialist in industrial screening.

Product category: Mould and die cleaning equipment


Ultrasonic cleaning has become an integral part of industrial production processes. The elimination of fouling is important for process reliability, prepares further process steps and is suitable for the final cleaning of products. 

The versatile ultrasonic components from Telsonic optimally fulfil the requirements of our customers' increasingly complex applications. They can be flexibly integrated into automated cleaning installations, despite the tougher production requirements.

Telsonic has decades of substantiated experience in industrial cleaning and continuously refines its products. Telsonic ultrasonic components are able to optimally deep-clean complex shapes (including blind holes, for example) to be optimally and thoroughly cleaned.
