Therefore, In order to provide high contact pressure enough to conduct solid welding for the split AA7075 materials in welding chamber, the specific die cavity design has been finished.
Therefore, multiple dies are produced to meet the standards of the extrusion process, and die cost is increased greatly due to waste of materials, manpower and time.
