Everything You Should Know About Aluminum Extrusion

Aluminum extrusion has seen substantial growth in application in product design and manufacturing over the past few decades. Although they are frequently a part of window or door systems, their uses are not limited to those. Aluminum bars are used in a wide variety of construction and manufacturing processes, so each product's quality must be unsurpassed.

Let’s see what aluminum extrusion is, the types of extrusion, the different shapes of extrusion, and where they are used.

What is aluminum extrusion?

Using the aluminum extrusion method, an aluminum alloy can be formed into an object with a clear cross-sectional profile for a variety of functions. The special combination of physical properties that aluminum possesses is best utilized during the extrusion process. Despite being one-third the density and rigidity of steel, aluminum's flexibility makes it easy to mill and cast, and the product offers durability and stability, especially when mixed with other elements.

Different types of extrusion

There are two hot extrusions.

●       Direct extrusion

●       Indirect extrusion

Direct extrusion

The quickest production method is direct extrusion. The process that is most frequently used to make aluminum extrusions is this one. In it, the ram pushes the billet through the die hole while the die is stationary. The forward or direct aluminum extrusion process is the name given to this technique since the blade and rams both move ahead at the same time.

Indirect extrusion

In the indirect extrusion process, the component on the end of the ram works against the blade while the billet itself remains immobile. By doing this, the pressure required for aluminum to move through the die is created.

This is the indirect press's principal benefit since it makes it possible to press tougher metals and items with narrower cross-sections because the smaller extrusion forces allow for lower pressing temperatures and, as a result, higher extrusion speeds. In turn, productivity rises.

Different shapes can be extruded.

Extruded shapes fall into three broad categories:

●       Solid, no contained spaces or apertures.

●       Hollow, void-filled in some places.

●       semi-hollow, having a partially contained void.

 Where is aluminum extrusion used?

There are countless uses for aluminum extrusions in the construction and manufacturing industries, including the creation of window and door systems. The angled form, which we carry in simple mill finish, pre-anodized, and pre-powder painted versions in black and white, is the most common extrusion from ATC. These straightforward right-angled designs can have sides that are equal in length or varied in length, and they can have various wall widths.

Round tubes, square tubes, and rectangular hollows are a few of the more common aluminum extrusions. Additionally, we offer solid pieces, including square, round, and flat bars. For a large number of our clients, ATC creates unique shapes. However, keep in mind that because of the expense of new dies, aluminum extrusion should be viewed as a volume process.

 Conclusion

Aluminum extrusion is the most versatile way of working with aluminum in a manufacturing setting. Extrusion has been impacting the material industry for many years, and it has contributed to numerous developments that have affected the rest of the industry. In other words, aluminum extrusion is not a technique used by an individual company or a group of companies — rather, it is a method that affects every corner of the global manufacturing industry.
