The company is investing a total of around €70 million in expanding production at the site. With this investment, the Strategic Business Segment DBS - part of the division Diehl Metall - is sending a clear signal in support of the Röthenbach an der Pegnitz manufacturing location. At the same time, the family-owned company Diehl is underlining its long-term commitment to the future of Germany as manufacturing location.
Production for new materials and sustainable processes
With this investment, DBS is responding to fundamental changes in market requirements, particularly stricter regulatory standards and the growing demand for lead-free brass alloys. These lead-free alloys represent a technologically demanding transformation for the industry - they not only place significantly higher demands on forming technology and the entire process chain but also elevate manufacturing to a new technological level.
The new production environment makes it possible to implement modern manufacturing technologies, further automate production processes, and at the same time use resources more efficiently. A high degree of automation, optimized material flows, and the use of energy-efficient technologies help to significantly reduce energy consumption and internal transport routes. This goes hand in hand with the continuous focus on sustainability within the Diehl Group.
Modern manufacturing based on LEAN principles can only succeed with strong partners. Therefore, in the selection of our suppliers, technical capabilities and long-term business relationships are essential.
Key components of the new bar production awarded
A central element of the new production line is the extrusion press for brass bar production. The contract for the entire hot forming process was awarded to the Presezzi Extrusion Group, which was able to present a compelling overall concept.
With reference to cold forming, which represents another key step in the production process, the long-standing business relationship with ASMAG GmbH will be continued. The company’s commitment throughout the course of the project and its own high standards of quality were decisive factors in awarding the contract.
As part of the eZee Factory, a new 12,000-square-meter production facility is being built at the Röthenbach site, designed to integrate seamlessly into the existing industrial environment. The contract has been awarded to BREMER SE, which will act as the general contractor. Groundbreaking is scheduled for May 2026, and the completion of the facility is expected by mid-2027.
Strengthening the Röthenbach industrial site
The investment of around €70 million is not only a technological step forward, but also a clear commitment to long-term industrial value creation in Bavaria. In a challenging economic environment, an investment of this magnitude is anything but a given. With the eZee Factory, a new building block for modern, efficient, and future-oriented brass production is being created in Röthenbach.
“We are making targeted investments in the future of our site and our technologies. At the same time, we are strengthening our competitiveness and creating the conditions to successfully meet customer requirements for new materials and sustainable solutions in the long term,” explains Heinz Strobl, CEO of DBS.
For the Diehl Group, a traditional family-owned company, the investment also represents a long-term perspective: Industrial innovation, sustainable production, and responsibility for its locations, and employees.
