Rohrbogen

Rohrbogen AG was founded in 1936 by Hans Schaffner. The visionary founder had previously acquired a special license. This allowed him to produce seamless elbows in Switzerland using the cold bending method. This business was a success from the outset. In the first year of operation, the workforce comprised 14 employees. Today, Rohrbogen AG employs more than 90 people at home and abroad. Our success is homemade Most of our special machines and manufacturing processes have been developed and optimized by us. The hot-presses put into operation in the 1950s were designed by us. In the 1970s hydro-forming, also referred as IHU (internal high-pressure forming), and the hydro-calibration of pipe arcs were added. This process was further developed in the 1990s to hydro-bending. Even today the special tools and gauges required for our production are manufactured in our in-house tool factory.
