MANUFACTURING METHOD OF TAIL-GATE INNERPANEL FOR VEHICLE

摘要

The present invention relates to a method for manufacturing the inner panel of a tail gate for a vehicle, wherein the inner panel is formed into a plate having curved parts and is bonded with a reinforcing material for improving stiffness, and the method comprises: a step of temporarily bonding a sub blank to be formed into the reinforcing material to a main blank to be formed into the inner panel; a step of forming the main blank into the inner panel and the sub blank into the reinforcing material in a forming mold; and permanently bonding the reinforcing material to the inner panel. The present invention for bonding the reinforcing material to the inner panel integrally forms the main blank (to be formed into the inner panel) and the sub blanks (to be formed into the reinforcing materials), thereby gaining effects for reducing the number of the forming molds and reducing manufacturing processes.
