Understanding the Process of Aluminium Extrusion

  • In recent years, the use of aluminium extrusion in product design and manufacturing has vastly increased, as has the number of aluminium extrusion suppliers. Perhaps you’ve heard of the process, but aren’t entirely sure on what the actual aluminium extrusion process is or how it works. Everything you need to know about aluminium extrusion, from what it is to the benefits it can offer, will be discussed below.

    What is aluminium extrusion?

    The process is relatively simple to understand. Aluminium extrusion is a technique whereby aluminium alloy material is transformed into objects by being forced through an opening. This opening is a die with a specific cross-sectional profile. The shape of the die determines the shape of the aluminium object.

    Think about the process of aluminium extrusion as the process of squeezing a tube of toothpaste. When you apply force, the toothpaste emerges from the tube in the shape of the tube’s opening. This opening of the tube essentially serves the same purpose as the die of the extrusion. Just like the toothpaste’s opening determines the shape of the toothpaste, so does the die of the extrusion determine the shape of the aluminium.

    The Different Shapes that can be Extruded

    Before getting into the specific shapes offered by aluminium extrusion suppliers, there are three different categories of extruded shapes. These include solid extrusions, such as bars; semi-hollow extrusions, such as angles or channels; and hollow extrusions, such as tubing.

    While the most common shapes that can be extruded are square bars, flat bars, round bars, square tubing and round tubing, some aluminium extrusion suppliers may even offer custom die designs and specialised extrusions.

    If you require a custom design, contact the several different aluminium extrusion suppliers and ask whether their specialists will be able to meet your demands.

    The Benefits Offered by Aluminium Extrusion

    These days, engineers and engineering designers require materials that are lightweight, strong and resistant to corrosion. Thereby, making aluminium an obvious choice, as it is one of the few materials capable of meeting all structural, thermal, aesthetic and acoustic requirements. Not only this, but thanks to aluminium extrusion, the need for additional parts is also reduced, as the objects and components created can be designed in such a way that they incorporate the necessary extra features.

    In terms of the environmental benefits, aluminium is completely recyclable and one of the most environmentally friendly metals. Unlike other recycled materials, when aluminium is recycled, it is able to retain all its properties of its original form. Thereby, making this material a highly economical and sustainable extrusion material.

    Finally, aluminium extrusion has innumerable applications across several different industries, such as in the architectural, automotive, electronic, and aerospace industry, to name a few.

    Now that you have a basic understanding of aluminium extrusion, it’s important to note that the suppliers of these components are able to offer said components in a vast array of sizes and shapes. Not only this, but reputable aluminium extrusion suppliers will also have sections available in different alloys.
