Aluminum extrusion is the process of shaping aluminum logs into the desired shape and use.  Aluminum is the preferred materials for tracks, frames, rails, mullions and heat sinks.  Thus, if you need any of these materials, you may need to understand how manufacturers do aluminum extrusion.


Applications of aluminum extrusion


These tracks, frame and rails are used for the following products:


  • aerospace products
  • architectural framing
  • copier components
  • modem housings
  • medical equipment
  • circuit boards
  • cable management products


If you wonder how aluminum extrusion is done, here is a short explanation of aluminum extrusion process.  This article hopes that you understand the importance of the process and the many uses aluminum extrusion has to different industries.


Before we move on to the process, let us look at the advantages of aluminum extrusion.


  • Aluminum is a lightweight material that is flexible.  It can be shaped into the desired form to help it become stronger.


  • Aluminum extrusion has a high strength to weight ratio, and thus its lightweight characteristic is huge advantage over other metal extrusions.


  • Aluminum is corrosion free in nature.  Thus, in industries where corrosion is common, aluminum has an added advantage.


  • Thermal and electrical conductivity is another advantage of aluminum extrusion over other metal extrusions.


  • Cost effective, because aluminum is easy to work on, lightweight and conductive, it is the most cost effective extrusion material.


Now, let us see how aluminum extrusion is done.


  • You will need to apply 800-950 degrees Fahrenheit into the aluminum log and pass it to the smelting machine. 


  • It will then be soft enough to be lined into the die.  You will need an extrusion press and the ram of the extrusion press will put pressure into softened aluminum billet and lead it into the die.


  • Nitrogen gas or liquid nitrogen will help cool down the aluminum after undergoing the smelting machine.  It needs the cooling to make the outer skin harder to be able to line it properly into the die.


  • After the die, the exit temperature will be lower to make the aluminum extrusion material easy to handle.


  • After this, the aluminum extrusion shaped in the die will be placed in a stretcher, straightened and hardening work will be applied.


  • The final step is the sawing of the aluminum extrusion into the required length.


There are several machines involved in this process and several other materials necessary to complete it.


Thus, if you need strong materials like aluminum extrusion you will need to acquire it from reputable suppliers.  Some people who want to do it by themselves may not be able to perfect the process.  Availability of the machines and experience of the extrusion worker is often necessary for a reliable finished product.


You may try working on aluminum extrusion yourself but the guarantee that it will be what you need it to be may not be possible.


While this article hopes to help you understand aluminum extrusion process, working it yourself may not be a good recommendation.  However, you can always try.
