Change of ownership and management at Gravostar Technologies

March 31, 2025 by Chris-Websupp-Gravostar

All change at SEH Technik GmbH: Urs Schiltknecht is handing over “SEH Technik GmbH – gravostar technologies” to new management

After more than 30 years of successful business activity, Urs Schiltknecht is handing over his company to Patrick Wirz as the new owner. The company SEH Technik GmbH – gravostar technologies is active in the field of mechanical deburring and labelling tools. During his long business career, Urs Schiltknecht has successfully launched various innovations on the market and supplied them to well-known customers worldwide, thanks to his focus on the two application areas of “deburring” and “marking”. His motivation was always to offer customers solutions to unsolved problems. This drive is still felt today and has a lasting influence on the company.

Patrick Wirz will lead the company operationally into the next phase as managing director together with his employees. Urs Schiltknecht will continue to make his expertise available to the company over the next few years as the inventor of patented tool solutions. He continues to strive to make a significant contribution to the design of innovative products of the future and will therefore take over the management of the technology department at Gravostar with passion and expertise.

About Patrick Wirz the person

Patrick Wirz, 39, grew up on the Swiss side of Lake Constance. He is married and has three children aged 5, 7 and 8. After his initial training as a polymechanic with a vocational baccalaureate, he completed his studies as a mechanical engineer (MSc) at the Technikum in Winterthur. Between his bachelor’s and master’s degree, he gained professional experience in orthopaedic research at the IORE in Houston, Texas. After his return to Switzerland and the successful completion of his studies, he started at the company Humbel in Kradolf. He began his professional career as a development engineer and over time was able to successfully take on a wide range of technical tasks as well as responsible management positions. His professional career initially led him to the position of technical director, then to group CTO, before he took on the role of CEO of Humbel Zahnräder AG with great commitment and success over the last four years. During this time, he also took charge of other areas and departments on an interim basis. He first completed the intensive SME studies programme alongside his job, and later expanded his expertise with an Executive MBA from the University of St. Gallen.

Patrick Wirz says about his move:
“The company’s future success is built on its excellent technical products, highly trained employees and the current high market potential, which provides a solid foundation for the company’s future success. My aim is to further develop and expand the established approach as a solution provider in the field of deburring and marking tools. Customer benefits will always be at the centre of our considerations, now and in the future. In order to provide our customers with the best possible support, we will not only focus on further developing our application technology, but also on establishing trade partners in foreign markets. Cooperation and collaboration with machine OEMs and technology partners will be key. Here, too, the aim is to make the best possible decision and ensure the highest quality.”
