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
reduction.

Adhesion

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
