About Aluminium Extrusions
Extrusion is a manufacturing technique used to create complex shapes and profiles with an excellent finish. Many materials can be used in the extrusion process including metals, polymers, ceramics and even food stuffs. It is a process used to manufacture products that have a fixed, cross sectional profile. Aluminium can be extruded either hot or cold and typical applications for aluminium extrusion include frames, tracks, rails and mullions.
In the extrusion process, the aluminium (either heated or cold) is pushed through or drawn through a die of the desired shape and cross section of the finished product. The aluminium will then assume the shape of this die creating a profile. The advantages of using an extrusion process is that you are able to create a very complex and intricate profile with exceptionally precise measurements. Also, because the aluminium is only exposed to compression and shear forces during the manufacturing process it retains much of its strength and structural integrity.
The aluminium extrusion process is one of continuous production. This gives great flexibility to the customer as profiles can be created for any length required from massive rails or tracks that are metres and metres long down to very short, centimetre profiles used for frames or 3-D printing.
With any aluminium extruded product you can expect to see a high quality finished product. The exterior of the profile will be clean and smooth as a result of the precision engineered dies used to form it and the cross section will be consistent from beginning to end.
