The present invention relates to a method for manufacturing a product with a spatially structured surface from a semi-finished product, a semi-finished product required for this purpose and a product produced in this way. The method is characterized in that a patterned target bending location is produced in the semi-finished product, and in that the semi-finished product is then subjected to a pressure over its surface, which is dosed in such a way that the pressure causes a plastic deformation of the semi-finished product along the target bending location, so that a product with a spatially structured surface is produced.

The invention relates to a manufacturing method for a crash frame of a battery compartment for electric drive vehicles by using metallic sheets which are arranged on top of one another and fixed together and which form in a following step a space by using an inner active media forming process to create walls of a crash frame whereby the space works as a deformation space to protect the battery modules inside the battery compartment against an impact. The invention further relates to the use of the crash frame for a battery compartment.
