Indirect Aluminium ExtrusionWith indirect extrusion, the die situated at the front end of a hollow stem moves relative to the container. The die is either pushed through the container or the container is pushed over the die. There is no relative displacement between the billet and the container liner. Therefore one advantage of the indirect extrusion process is that there is no friction, during the process, between the billet and the container liner. The metal flow is more uniform during indirect extrusion than direct. This usually relates to better section uniformity along its length. A discard/butt is produced as with the direct process, which is handled in the same way. The extruded profile is again transferred on to the press’s handling system.For more information on Indirect Aluminium Extrusion please contact us.
