Ultrasonic welders

Precise cuts and ultrasonic welding with a digital control of the parameters

Easy to use, easy to programme with unmatched precision of welding.  DIGITAL Thorn+ welder and its wide spectre of possibilities is on a par with top class welders ( SUPER Thorn), produced using the same technology, perfectly suited for the most challenging applications.

It guarantees maximum repetitiveness of the welding process, high reliability, and shorter working cycle. Designed for tasks, where output parameters control  is essential and the ability to generate charts is not as important.

Standard frequencies are 20, 30, 35 and 40kHz.

Proven, reliable control panel Thorn+

Designed for fast, easy and transparent communication interface between the machine and the operator. Thanks to it, all parameters or welding effects control becomes pure pleasure.  
Constant parameters control within independently defined rules, leads to higher quality of the welding process.

In a case when certain different elements are being welded , we can define up to 128 different memory entries , which can be chosen externally. The possibility to set initial downthrust pressure and the pressure while welding enables obtaining the best possible connection ( 4 pressures available) . Additionally we are able to control such ad-ons as rotary table , soundproof cabin, adjustable table, tape drive etc.  And the history of welds performed ( both correct and incorrect ones) we are able to export via RS-232/485 protocol.

Available welding options:

  • Time: welding using constant time
  • Energy: welding using constant energy
  • Power: welding using constant power
  • Total depth (ABS): welding to a given depth
  • Relative depth (DRM): welding to a given depth
The depths is calculated from the moment the detail meets the deliverance power

Digital control panel,  SONICTECH’s precision

Every Thorn+ DIGITAL series machine has been equipped with pressure control technology using proportional valves. Using that we are able to set, with digital precision, each of the pressures required (every 0,1 bar)

P1 – deliverance pressure
P2 – welding pressure 1
P3– welding pressure 2
P4 – holding ( cooling ) pressure

The welding path is controlled with a precision up to 10μm, thanks to the implementation of position encoder.

All of the above wouldn’t be possible if we weren’t able to sustain welders stiffness, which we obtained by using special combination of iron and aluminium (35kHz)


SONICTECH industry solutions are the answer to the specific requirements of our clients. By developing a personalized ultrasound technology, we rely on innovation and a broad range of experience of our specialists.

Automotive industry

Durability and safety

When it comes to connecting over 10 000 thermoplastic elements of a car, ultrasound technology ensures precision, recurrence, aesthetics and durability.

Welders designed for automotive industry ensure that all necessary criteria to optimize and validate the processes of welding many components are met.

Consumer industry

Flexible production

Constant innovation when it comes to household articles market ensure growing consumers’ expectations and demands. With the equipment being used everyday what counts the most is robustness, durability, precision, perfect design and neat surface finishing.

Thanks to the ultrasound welding technology the economical way of connecting different components is accessible.

Food industry

Ideally cut edges

The ultrasound technology works perfectly when it comes to cutting food products – especially those crispy, cream and soft. With the use of ultrasounds the product’s shape remains unchanged what means it is possible to cut very thin slices.

Minimal surface friction guarantees clear cut with minimal product Mount on the knife. Fast and clear cut maximises productivity and minimises clearing time.

Textile industry

Comfort and hygiene

The fast process of welding textiles enables production of soft and safe everyday use products. There is a possibility to simultaneously letter, laminate and cut products. Laminated elements are much more comfortable and practical. The ultrasound cuts lack in fibres and ensure clear, specific finishing.

Furthermore soft surfaces do not get damaged when lettered using ultrasound.

Packaging industry

Keep it fresh

The ultrasound technology can be used for welding food packaging and other products. Thanks to the highest precision the packaging is robustly closed, better protected, and remains fresh longer.

Ultrasound welding machine is a more economical and more productive alternative to other packing methods.

Medical industry

Health and safety

The ultrasound welding technology is irreplaceable when it comes to medical products, where it is necessary to meet strict constrains regarding safety elements. Welding ensures robustness, durability, minimal particles production and stability of the production process.  

Ultrasound welding ensures precise process control, identification and data collection for future.

Other industries

Endless possibilities

Thanks to its reliability and speed ultrasounds are widely used in the construction industry, where it is necessary to weld different components used to secure and harden the basis.

Ultrasound technology enables precise joining of elastic synthetic tapes to create solid spatial structures of the protective basis.
