Aluminum extrusion process: from start to final product
Aluminum extrusion is the process of forming aluminum profiles by extruding molten aluminum material through a special die-shaped hole. This method is widely used in various industries such as construction, automotive, mechanical engineering, electronics and others. In this article, we will look at the details of the aluminum extrusion process, from material preparation to the final product.
Preparation of material
The first step in the aluminum extrusion process is material preparation. Aluminum products are made from 6063 alloy grade with T6 heat treatment. In addition, we produce from recycled aluminum, which allows us to reduce production costs and contribute to preserving the environment. To prepare the material, it is melted and cleaned of impurities. The molten aluminum is then transferred to the cylinder of an extrusion press.
Extrusion press
Extrusion press is the main equipment used in the aluminum extrusion process. In the cylinder of an extrusion press, aluminum reaches a certain temperature and pressure to obtain the necessary plasticity. It is then pressed through a sharp-shaped hole using a press piston.
Press machines have different capacities - from several tons to tens of tons. The choice of press power depends on the requirements for the final product. There are also presses of different sizes to produce different sizes and shapes of profiles.
Cooling and cutting
- Cooling: After extrusion, the aluminum profile goes to the cooling table, where it is cooled using water or air. This allows the profile to lock in place and maintain its shape.
- Cut-off: After cooling, the profile is cut to the required length. This is done using a special saw or cutter. The cut profiles are ready for further processing and use in production.
Processing and finishing
After cutting, the profiles are processed and finished to achieve the desired appearance and characteristics. This may include the following processes:
- Profiling: Profiles can be subjected to additional profiling to create a special shape or relief.
- Heat treatment: Sometimes profiles undergo heat treatment to improve their mechanical properties. For example, annealing or hardening processes are used.
- Anodizing: Aluminum profiles can be anodized to provide a protective coating, improve corrosion resistance and give them a decorative appearance.
- Painting: Painting profiles allows you to create a variety of designs and color schemes in accordance with the needs of the customer.
- Mechanical restoration: In some cases, profiles require additional machining, such as cutting, drilling or routing, to obtain the desired holes or shape.
Uses and benefits of aluminum profiles
Aluminum profiles are widely used in various industries due to their unique characteristics and advantages:
- Ease: Aluminum is a lightweight material, making it ideal for use in structures where weight matters, such as in the automobile and aircraft industries.
- Strength: When properly processed and heat treated, aluminum extrusions can have high strength, allowing them to be used in demanding engineering and construction projects.
- Corrosion resistance: Aluminum is highly resistant to corrosion and therefore does not require additional protection from the environment.
- Processing flexibility: Aluminum is easy to machine and can be easily bent, welded and folded into the desired shape.
- High temperature resistance: Aluminum retains its properties at high temperatures, making it ideal for applications under high thermal stress.
Aluminum extrusion is an efficient way to produce aluminum profiles with a wide range of applications. The process begins with the preparation of the material and ends with the processing and finishing of profiles in accordance with customer requirements. The final products may have different shapes, sizes, colors and characteristics depending on their intended purpose. Aluminum profiles are a reliable and sought-after material for the implementation of various projects, having strength, corrosion resistance and flexibility in processing.
