Extrusion is the process whereby objects of cross-sectional profile are created. The process involves a series of complex procedures. Aluminium extrusion is therefore, the process of taking aluminium alloys and shaping them into objects with a cross-sectional profile. Being one of the most abundant elements, it makes up about 8% percent of the earth crust. It has numerous properties such as being ductile and malleable, soft and lightweight. It can also be non-magnetic and has a shiny silvery appearance. Its lightweight nature allows it to be cast, drawn, and extruded.
The process of extruding it is quite complex and involves a number of steps, the first one being designing and creating the shape of die. After the completion of this, an alloy having a cylindrical shape is heated at high temperatures of between 800F and 925F after which it may be transferred to a loader. In order to prevent it from sticking to the extrusion machine, a lubricant is applied.
Pressure is then applied as the second step. A substantial amount of pressure is subjected to a dummy block. This in turn creates a pushing effect so that the billet is forced into the die. In order to prevent the formation of oxides, nitrogen rich air or liquid is passed through the die sections.
The extruded material, which now possesses the same shape as the die is then allowed to pass through a run-out table. It is then brought to a cooling table where it might be cooled down. Once the cooling process is done, it is transferred to a stretched for straightening and hardening processes to take effect. Using the saw, it might then carefully be cut into the required length.
The pieces are then taken under a series of heat treatments as the final step takes effect. They are put into age-ovens where they are further hardened. Various adjustments can also be made in the final stage such as color and brightness enhancements. The advantage of this process is that a series of extremely complex shapes and sizes can be created; it also has a fine finish.
The extrusion industry has continued to see a lot of growth as well as development. It has seen the introduction of new techniques to make the process a lot easier and more efficient. This element has a variety of applications. It might be used in the manufacture of various household items such as cooking utensils, watches among others. It can also be used in making of streetlight poles, walking poles, food, and beverage containers, cases, foils among many other widely used items.
As mentioned above, it is lightweight. In addition to this it can be corrosion resistant and also non-flammable. It is these great features that make it the most appropriate material to be used in various industries such as the aerospace, construction, and transport industries. Its ability to conduct both thermal and electrical energies makes it the perfect material to make superconducting lines.
Finally, because of its durability it is widely used to make consumer products such as tablets, smartphones, and laptops among other gadgets. This kind of metal is by far one of the best metals. Apart from having great qualities, it can also be recycled.
