FACTORS RESPONSIBLE FOR EXTRUSION
Extrusion is the forming of other objects from the aluminum alloy. Purposes of different cross-sectional profiles are formed. The raw aluminum is also known as billet. For extrusion, the billet is heated to high temperature. The temperature may vary according to the objects, after reaching the desired temperature the billet is added to the loader, and the lubricant is attached to it which prevents the billet from sticking. For further aluminum extrusion profiles, the billet is transferred to the cradle. The pressure is applied by the ram which pushes the billet inside the container.
The raw aluminum or billet is moved inside the container, and then the pressure is applied. The billet is crushed against the die and broke into smaller walls so that it comes into contact with the container walls. Liquid nitrogen flows along the walls and cools the aluminum. The applied pressure make the firm metal squeeze which helps in the transformation into another object which is aluminum extrusion profiles. Extrusion is pushed, the metal is guided along with the run-out table. It is cooled by fans which are there along the whole length of the run-out.
Billet which is not used in aluminum extrusion profiles is known as butt. The butt which remained contains traces of oxides from the skin of the billet. It is discarded, and the other billet is added, and like this, the extrusion process continues. After reaching to the required length, the extrusion is cut, and the metal is transferred via the belt. The metal is then moved from the runout table to the cooling table where it is cooled down completely.
After the cooling process, the stretching is done, and this increases the durability of the metal. Finishing is the final step which improves the strength of the metal.
