Aluminum is so widely used today that there is hardly a corner of our lives where we don’t come across it on one form or another. This is particularly so in the fields of construction and interior decoration/design.
Both Home & Office
If you are a boss at work, maybe you get your own office, but, for many of today’s office workers, a work station inside a partitioned off cubicle is the best they can hope for. Probably, they notice the color and texture of their partition (whether it is floor to ceiling or only partial height) but, how many realize that they are possibly surrounded by extruded aluminum shapes? Something has to support the partition panels. Something has to hide the mess of wires and cables feeding your workstation. These “somethings” are often made of aluminum and their shape is usually produced by extruding aluminum through a die on an extrusion press. Quite possibly, if you have a window, its frame will also be of aluminum.
The same concepts will also be found within many residential homes (and hotels for that matter). Some of those shapes may be basic standard profiles like channels or T-pieces. Others could be in a Custom Aluminum Extrusion shape chosen by the designer, either to fulfil a particular function in the construction of his modular office system, or, maybe only chosen for purely aesthetic reasons. Aluminum is a popular choice because of its affordable price and the nearly infinite variety of shapes that it can be extruded into.
Principles Of Extrusion
Whether to a standard shape, or, a Custom Aluminum Extrusion shape (often called a profile because the shape description is applied with respect to the cross sectional view), the process starts with a billet of the raw material (i.e. aluminum, but, for practical reasons, this is usually an aluminum alloy). The billet, with a larger cross section than the final, extruded product, is placed in a chamber (which it precisely fills). One end of the chamber is closed off by the head of a movable ram. The other end of the chamber holds the die – which is basically a shaped hole in a thick metal plate.
Once the billet is totally enclosed in the chamber, (hydraulic) pressure will be applied to the remote side of the ram causing it to move further into the chamber. However, the billet is taking up all available space in the chamber. However, aluminum is ductile and, under the ram’s force, the billet will start to flow out through the hole in the die. The shape of the hole in the die decides the Custom Aluminum Extrusion shape that exits through that hole.
