PLATES OF DIFFERENT MATERIALS FOR A CAR AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a method for manufacturing a plate made of different materials. The plate comprises: a first plate having a plurality of coupling grooves, where a melt solution for forming a coupling protrusion unit of a second plate penetrates, on the surface; and a second plate formed on the surface of the first plate and having the coupling protrusion unit formed by penetrating the coupling grooves of the first plate. The present invention maximizes a coupling force between two members composing the plate made of different materials to prevent a gap between the members.
