Long-arm 700

We have more than 40 years experience in welding technology. Starting with the welding production of personal protective equipment, today we are in high-tech engineering and software development for ultrasonic welding for a wide range of different applications.

Our machines offer considerable advantages in many applications, for example through the roll seam method – also individual designed special machines are part of our product portfolio! If you have any questions feel free to contact us or one of our partners. We also create welding samples for you also from your material.

The future of ultrasonic welding

A modern ultrasonic welding machine needs performance, flexibility and must easy operate.
The new NUCLEUS generation of the long-arm 700 uses high-tech components to make a precise working at highest level possible. Numerous features allow an individual machine configuration for maximum productivity and reproducibility in serial production. 

The new generation of machine sets new standards in the world of welding products. This includes the brand new software package that makes it easy for both beginners and experienced professionals.

The newly developed DX1 ultrasound package ensures absolutely precise and constant amplitude values, especially at high speeds and sensitive materials.

The generation DX1 can be obtained in addition to the standardized 400cm in 700cm and 1000cm width. This facilitates the welding of wide, heavy materials.

Machine highlights

Restrike Puller

NUCLEUS developed independently driven tightening puller to ensure high quality of smooth seams and enable restriking of the welding seams. Propulsion as well as the use of the puller can easily be operated via touch interface of the machine. The restrike puller apply extra pressure to the seam which considerably improves its strength. This is an important progress especially for materials with significant self-dynamics.

Wear Reduction

In the case of particularly thick material or fabrics which need lots of pressure and energy while processed the sonotrode must resist very high impact. Despite the enormous hardness a damage of the hardened sonotrode surface may occur. The legally protected NUCLEUS-FFW-CUT System offers a solution which saves costs as well as time. This wear reducing installation distributes the pressure of the cutting wheel on the whole surface of the sonotrode thus ensuring maximum durability of the sonotrode.
