The Erdmann Group
A group consisting of six medium-sized companies. Family-run. Industrial. Future-oriented.
Our manufacturing expertise
Our corporate group stands for technical expertise, modern manufacturing technologies, and cooperative partnerships. Our production range includes forgings in rough or machined condition, as well as pressed and stamped parts and components machined from solid material. We deliver ready-to-install or as blanks upon request.
Modern technology meets experience
Our companies operate with modern CNC machining centers, automated welding robots, induction hardening, as well as in-house tool and fixture manufacturing. The design of forging tools is centralized using modern CAD systems and years of engineering know-how.
Our promise
As a family-run corporate group, we continuously invest in modern manufacturing technologies, qualified employees, and efficient production processes.
Thanks to our high vertical integration, we can react flexibly to individual customer requirements – from the blank to the completely machined and coated component.
