A very special moment for DIENES: After nearly five decades with the company, Dipl.-Ing. Rudolf Supe-Dienes, Managing Director and member of the third generation of the founding family, is retiring at the end of the year.
With his technical expertise, inventive spirit, and entrepreneurial foresight, Rudolf Supe-Dienes has significantly shaped the development of the DIENES Group. Together with his brother, Bernd Supe-Dienes (†2021), he transformed the family business into an internationally leading provider of industrial slitting and valve technology – always driven by a commitment to quality, precision, and innovation.
Rudolf Supe-Dienes began his professional career at DIENES at the age of 16, completing vocational training as a toolmaker. Early on, he worked alongside his father and took on responsibility within the family business. Later, he managed DIENES together with his brother Bernd Supe-Dienes – a strong duo that led the company with courage, determination, and foresight.
Together, they expanded the product portfolio, opened up international markets, and continuously developed DIENES – always with the goal of passing the family business on to the next generation in the long term.
The transition to the fourth generation was planned early and implemented with foresight.
In 2021, the son of Rudolf Supe-Dienes, Julian Supe-Dienes, joined the company as Head of Sales and was appointed to the management board of the DIENES Group in 2023. His sister, Maja Supe-Dienes, also started in 2023 as Project Manager in Corporate Development and is now part of the management of Messerfabrik Neuenkamp GmbH, a sister company specializing in the production of high-precision tools.
Together with their father – and initially with their uncle Bernd – Julian and Maja have set the course for the company’s future in recent years. Both are following in great footsteps, continuing the family’s values of innovation, quality, teamwork, and a strong sense of family.
The fourth generation is ready to continue the success story. With a strong international team, modern production sites, and a clear focus on future-oriented topics such as digitalization and sustainability, the new generation is leading DIENES forward with fresh thinking and a deep awareness of tradition.
Rudolf Supe-Dienes will remain closely connected to the company – as a consultant, mentor, and inspiring personality, continuing to share his knowledge and experience.
The entire DIENES team would like to thank Rudolf Supe-Dienes for his exceptional lifetime achievements, dedication, and passion for precision and technology. Under his leadership, DIENES has been decisively shaped and a strong foundation has been laid for the future.
We wish Rudolf Supe-Dienes all the best for the time ahead and many wonderful moments beyond professional life.
