Tailored blanking

           Tailored blanking is a production method that
           involves joining materials of differing thicknesses
           or qualities before press forming them. Since it is
           possible to position materials of differing strengths,
           thicknesses, and qualities only where they are
           required, the method contributes greatly to weight

           Increasing the joint rigidity of each body part is directly linked
           to the improvement of the vehicle’s responsiveness and the
           quality of the ride comfort. Body rigidity is increased by
           surface bonding of the vehicle body joint portions, not only by
           spot welding but also by using an adhesive together with spot
                                                                                    Cockpit cross-car beam created by
