Abstract
This concerns a process for manufacturing extrusion sections made of a light weight metal, using an extrusion tool with a single hole die, whereby several extrusions are produced simultaneously using a common single hole in the die. The device for carrying out the process allows a movable steel strip to pass through the common die hole this dividing it up into separate extrusion chambers.
