Connection for the future
NUCLEUS GmbH can look back on more than 50 years of company history. The family-run business has been building its experience in welding technology since it was founded in 1976 by Dr. Florian Tschech.
Starting with the development and construction of fully automated machines for the welded production of personal protective equipment in 1978, we are now a specialist in the development of high-quality ultrasonic welding machines 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 the second generation of the family business. Based in Düsseldorf, Germany, we are working on the future of ultrasonic welding technology. With a large number of qualified and well-trained employees, we still develop and manufacture our machines in Germany.
Through our long company history and good relationships with our customers, NUCLEUS has built a large network of business relations all over the world. We are constantly working on innovative, personalised and high-quality products to deliver the best products and service to our partners.
After moving to our new headquarters in 2019, we are ready for more challenging projects in the field of ultrasonic welding technology.
