Key features:

  • Rear seat structure for Opel Astra, Insignia and Buick Regal
  • 300 laser weld seams + additional MAG and projection weldings
  • Safety part, therefore 100% traceability of welding quality for each part necessary
  • E-coated
  • Stamping of profiles with rotary-benders and partly complex drawing parts with thicknesses between 0.5 mm and 2.5 mm and yield strengths up to DP1000
  • Structure separately validated by several types of static and dynamic tests, such as several crash tests


  • Laser welding “one shot + on the fly”:

    • No sub-assemblies necessary and very short cycle times

  • Profiles produced by stamping tools with rotary benders, allows most cost-efficient production
  • 100% traceability and control of all laser- and MAG welding seams and storage of results in a database. This enables verification of all parameters of each part every time, by checking the unique barcode sticker on each structure
