Automatic bolting system for car underbody assembly

Achieve precise underbody bolting in car assembly lines with a fully automated system that enhances production accuracy and efficiency, seamlessly integrating into existing processes to ensure reliable tightening and data synchronization.

The Flex Bolt Automatic Bolting System from Dürr is engineered to deliver unmatched precision in automotive assembly applications. This Cartesian axis system excels at automating the underbody bolting process, using fully controlled axes to enhance both capacity and precision. Designed for integration into automotive lines, it accommodates simultaneous multi-model production with programmable flexibility. The Flex Bolt system automates screw tightening and ensures data integrity by transferring critical bolting parameters to a central PC, enabling real-time quality control. The system’s direct communication with backup stations allows for automated repeat processes without manual intervention, optimizing production flow. Ideal for industries beyond automotive, such as mechanical engineering, chemical, pharmaceutical, and woodworking, the Flex Bolt system supports a range of end products from engine assemblies to pharmaceutical capsules.
