Connection for the future

NUCLEUS GmbH can look back on more than 40 years of company history. The family run business is leading the experience in welding technology since it’s founding in 1976 by Dr. Ing. Florian Czech.

Starting with the development and construction of fully automated engines for the welding production of personal protective equipment in 1978, we are now a specialist in the development of high quality ultrasonic welding engines made in Germany. 

Through intensive research and further development of continuous ultrasonic welding technology with rotating sonotrodes, today we are a high-tech engineering company and also a software developer for ultrasonic welding machines.

With our current Managing Director, Marc Tschech, we are already in our second generation of the family business. Based in Dusseldorf, Germany we are looking for the future of ultrasonic welding technology. With a large number of qualified and well trained employees, we develop and manufacture our machines still in Germany.

Through our 40 years company history and good relationship to our customers, NUCLEUS has build a huge network of business relations all over the world. We are always trying to working on our innovative, personalised and high quality products to deliver the best products and service to our partners. 

After moving to our new headquarter building in 2019, we are ready for challenging more projects in the field of ultrasonic welding technology.
