Tailored blanks are metal panels made of layers of different material grades in varying thicknesses and strengths. They are supplied as semi-finished products for manufacturing car exterior parts. These tailored metal panels are selectively reinforced by additional material layers at points or areas which will be exposed to high stress loads in service. Their structural strength can be improved still further by the use of special reinforcing adhesives.
In this process step, Openair-Plasma® pretreatment assures secure adhesion of the material layers. This combination provides distinct advantages in terms of low weight of the components plus increased crash safety.
