Aluminum Extrusion Services
Customization
We offer custom aluminum extrusion profiles, and we can combine extrusion with other manufacturing methods such as CNC milling, turning, and bending to make the final parts.
Low Volume
Most extrusion companies set very high MOQs. Leading Edge doesn’t, so we are the best choice for lower volumes. One-off prototype extrusions or a few hundred units? No problem.
Fast Delivery
If you don’t want to wait 30+ days to get your extrusion mold and profiles manufactured, come to us! We can finish everything in half the industry-standard time or even less.

Aluminum Extrusion
What is Aluminum Extrusion?
Aluminum extrusion is the process of shaping aluminum material by forcing it to flow through a shaped opening in a die. When extruded in this way, the aluminum material comes out of the die as an elongated piece with a continuous cross-sectional profile, and this profile can be highly complex and detailed. For non-specialists, an easy explanation of extrusion is to think about how pasta shapes or Play-Doh are made. In both cases, dough is fed into a chamber, pressure is applied by turning a crank or handle, and strands of the stuff are squeezed out of a small hole. Changing the attachment for this hole affects the cross-section of the strands, giving you the choice between e.g. tagliatelle, penne, or something else.
Of course, aluminum billets aren’t quite as malleable as pasta dough, so the aluminum extrusion process requires a lot of force — typically via huge amounts of hydraulic pressure — and, in some cases, the application of heat.
How Does Aluminum Extrusion Work?
The aluminum extrusion process can be carried out in one of two ways: hot extrusion or cold extrusion. There are reasons to use both methods. Hot extrusion allows for greater volumes of aluminum to be fed into the die, quickly and at lower pressure, while cold extrusion can produce mechanically superior parts with a good surface finish and resistance to oxidization.
To extrude aluminum via the hot extrusion process, aluminum billets must first be cut to an appropriate size. They are then heated in an oven to a temperature between 300 °C and 600 °C, making the metal supple but not liquid.
When the cut aluminum billets are heated, a ram powered by hydraulic pressure forces them into the die, which may have a standard aperture (i.e. a round or square hole) or a custom-made profile. A huge amount of pressure — around 10,000,000 pounds — is required to force the heated aluminum through the die.
The extrusions are then cooled on a cooling table, before being cut into lengths according to the customer’s demands. Heat treatment can also be applied to harden the aluminum.

Standard Aluminum Extrusion Profiles
Custom aluminum extrusion profiles can be cut to any 2D cross-sectional shape. However, there are several standard aluminum extrusion profiles suitable for many projects, including extruded aluminum bar and extruded aluminum channel of various forms.
Standard profiles include:
- Circular bar
- F-shape
- C-shape
- J-shape
- Square tube
- Square bar
- Circular tube
- T-shape
- L-shape
- U-shape

Custom Aluminum Extrusion Profiles
Standard aluminum extrusion profiles (like extruded aluminum channel or extruded aluminum bar) are typically mass manufactured by extrusion specialists; if you need large quantities ofp standard extruded aluminum profiles, you are better off using the services of one of these companies.
However, for custom aluminum extrusion profiles with a nonstandard aluminum extruded shape, Leading Edge may be a better option. That’s because we accept low-volume extrusion orders — for prototyping and small batch production — allowing you to experiment with custom profiles.
In addition to creating custom aluminum extrusion profiles using custom dies, we can combine extrusion with other manufacturing processes (like CNC machining) to produce custom final parts. This can allow us to make parts faster and more affordably, especially if the majority of the part has a consistent cross-section.
