Aluminum
as a metal has been used to produce a wide range of products for varied
uses. Since its discovery in 1827, every year more and more uses are
found for products of extruded aluminum. Aluminum extrusion can produce
everything from the most common large extruded profiles as well as
thin-wall extruded profiles. One common and one of the most popular
product of aluminum extrusion is packaging material.
Aluminum extrusion process
Aluminum extrusion is defined as the process of shaping aluminum by
forcing it to flow through a shaped opening in a die. Extruded aluminum
comes out as an elongated piece with the same profile as the die
opening. The most important factor to remember in the aluminum extrusion
process is temperature because it gives aluminum desired characteristics
like finish and hardness.
Factors to be considered for extrusion
A wide variety of shapes can be extruded in aluminum extrusion, but
there are limiting factors to be considered such as follows:
- Extrusion ratio
- Size
- Shape
- Alloy
- Tolerance
- Tongue ratio
- Finish factor and
- Scrap ratio etc.
