In this research AA6060 alloy was used and was extruded at 25m/min, 30m/min, 35m/min, 40m/min and 45m/min for a particular profile. The highest exit temperature increased from 542°C to 567°C when the extrusion speed was increased from 25m/min to 45m/min. Three types of die pick-up were identified. They were named as normal pick-up, die line pick-up and lump pick-up. Normal pick-up occurred regardless of the extrusion speed and exit temperature; however the amount of normal pick-up did not increase when the extrusion speed was increased. Die line pick-up occurred when the extrusion speed was...
