Introduction to START-STOP Technology
Dreistern introduced START-STOP® Technology 30 years ago, revolutionizing rollforming lines by integrating numerous post-rollforming operations such as punching, embossing, and welding. This technology allows for the production of finished profiles in a single line process, eliminating the need for costly secondary operations and simplifying assembly.

Integration of Laser-Welding
The integration of laser-welding into the START-STOP® process marks a significant advancement. This allows for the production of laser-welded profiles using robust, low-maintenance CO2 lasers from TRUMPF Lasertechnik, with welding power up to 10 kW and speeds up to 25 m/min.
