Knitting for Environmental Protection
Interview with Alfred Buck, Managing Director of Buck GmbH & Co. KG
In the automotive industry, technical innovations and sustainable solutions are crucial for success. Buck GmbH & Co. KG specializes in the production of damping elements that stand out due to their heat resistance and compact design. At the same time, the company is developing environmentally friendly applications such as biodegradable tree protection covers. In an interview with Wirtschaftsforum, managing director Alfred Buck explains how technology and environmental protection can work hand in hand to create future-proof products.
Wirtschaftsforum: Mr. Buck, what have been the most important milestones since the founding and how did the development of the first knitting machine come about?
Alfred Buck: Buck Maschinenbau GmbH was founded in 1958 by my father. A crucial milestone was the development of a special knitting technique that made it possible to form tension-free stitches at a higher speed. This technique allowed us to process brittle fibers such as glass, carbon, and basalt fibers. Originally designed for knitting carpet yarns, these machines could knit 20 to 30% faster than conventional machines, which represented a significant advancement for our company.
Wirtschaftsforum: How did the transition to metal knitting come about?
Alfred Buck: The transition happened rather by chance. To save money, a cheap steel wire was used for weaving into the new machines. A customer discovered the metal knit and recognized the possibility of using wire knit as filters for the automotive industry. Now, damping elements made from knitted stainless steel wire are our main business. We have over 30 years of experience in manufacturing these products. Initially, we developed damping elements for the exhaust area and supplied them in series, but new applications have since been found, such as in propeller shaft couplings. These elements offer advantages such as heat resistance and the ability to transmit a higher torque with minimal space.
Wirtschaftsforum: What other applications are there for this technology?
Alfred Buck: We have recently started a new project that includes heat-resistant seals. These seals can compensate for tolerance variations in sheet metal parts. We use a combination of graphite and special wire that can withstand temperatures up to 1,000 °C. Carbon fiber knit also offers great advantages as a matrix for ceramic brake discs.
Wirtschaftsforum: What other areas have you recently entered?
Alfred Buck: One new area is biodegradable tree protection sleeves. These are used to protect young trees in the forest from being eaten by wild animals. Unlike traditional plastic covers, they decompose without leaving microplastic. We use a special hybrid material that is lightweight, flexible and environmentally friendly.
Wirtschaftsforum: That is a remarkable step towards environmental protection. How did you come up with this idea?
Alfred Buck: The idea arose when we became aware of the problems caused by plastic in the forest. We wanted to find a solution that was both functional and environmentally friendly. After intensive research and development, the German Institute for Textile and Fiber Research (DITF) developed a material that meets all the requirements.
Wirtschaftsforum: How is the distribution of these new products going?
Alfred Buck: So far, we have already sold 300,000 of these tree protection sleeves. We also participated in the world's largest forestry exhibition and received very good feedback there. The demand is great and we hope to gain a significant market share.
Wirtschaftsforum: What about your marketing strategy? In which direction would you like to develop in the future?
Alfred Buck: We do not want to rely exclusively on the automotive industry. Therefore, we are focusing on breaking into new markets, especially in the areas of environmental protection and sustainable solutions. We are diversifying our product range and developing innovative approaches.
Wirtschaftsforum: What role does digitalization play in your company?
Alfred Buck: An increasingly important one. My sons, who are now in the 3rd generation of the company, bring fresh ideas and technical know-how. We are working on automating many processes and making production more efficient.
Wirtschaftsforum: How are you dealing with the skilled worker shortage that many companies in Germany are experiencing?
Alfred Buck: It is indeed a challenge. We are constantly looking for qualified employees and try to expand our team. Training young talent is important to us and we also offer internships and apprenticeships to promote the next generation of skilled workers.
Wirtschaftsforum: What are your goals for the future?
Alfred Buck: We aim to increase our sales while diversifying our product range. We see great potential in the areas of environmental protection and sustainable solutions. The market is constantly evolving and we need to plan ahead.
Wirtschaftsforum: What personally motivates you to come to work every day?
Alfred Buck: I really enjoy developing new products with the team and exciting customers. I think it's important for businesses to take responsibility and develop sustainable solutions. Everyone can make a contribution to making the world a better place. We need to think innovatively and be willing to take risks and explore new avenues.
