Production process of extrusions aluminium

Raw materials

Raw materials: The first step in the production process is selecting the appropriate raw materials. Aluminum billets are the primary raw material used in the extrusion process. These billets are typically made from aluminum alloys, which are chosen based on the desired properties of the finished product. For example, different alloys may be chosen for their strength, corrosion resistance, or conductivity. The billets are typically preheated to a specific temperature before being loaded into the extrusion press.

Heating and extrusion

Heating and extrusion: Once the billets are preheated, they are loaded into an extrusion press. The press consists of a chamber with a ram that pushes the heated billet through a shaped die. The die is made of hardened steel and has a specific shape and cross-section that determines the final shape of the extruded aluminum. As the billet is pushed through the die, it is extruded into a long, continuous profile. The extrusion process creates a uniform cross-section and surface finish. The speed of the ram and the temperature of the billet can be adjusted to achieve different properties in the finished product.

Cooling and stretching

Cooling and stretching: Once the extruded aluminum profile has been created, it is cooled using air or water to ensure that it maintains its desired shape and properties. The cooling process can be critical in ensuring that the extruded aluminum doesn’t warp or distort. After cooling, the extruded aluminum may undergo stretching or other finishing processes to further refine its dimensions and properties. For example, the extruded aluminum may be stretched or straightened to achieve tighter tolerances or to improve its mechanical properties. Other finishing processes may include cutting, drilling, punching, or surface treatment.

Overall, the production process of extruded aluminum is highly customizable, allowing manufacturers to create precise shapes and properties to meet specific application requirements. By carefully selecting the appropriate raw materials, controlling the temperature and speed of the extrusion process, and using various finishing techniques, manufacturers can create extruded aluminum profiles with a wide range of properties, including strength, corrosion resistance, conductivity, and more.

Characteristics of extrusions aluminium

Lightweight and sturdy

Lightweight and sturdy: One of the most notable characteristics of extruded aluminum is its lightweight yet sturdy nature. Aluminum has a low density, which makes it much lighter than other metals, such as steel. Despite its light weight, extruded aluminum is also strong and durable. This combination of strength and lightness makes it an ideal material for a wide range of applications, from construction to transportation.

Highly malleable and workable

Highly malleable and workable: Another characteristic of extruded aluminum is its high malleability and workability. Aluminum is a very ductile metal, which means it can be easily shaped and formed without cracking or breaking. This makes it an excellent material for extrusion, as it can be shaped into complex profiles with precise tolerances. Extruded aluminum can also be easily cut, drilled, and welded, making it a versatile material for a variety of applications.

Corrosion-resistant and environmentally friendly

Corrosion-resistant and environmentally friendly: Extruded aluminum is naturally corrosion-resistant, due to the thin layer of oxide that forms on its surface when exposed to air. This oxide layer helps protect the aluminum from corrosion and other forms of damage. In addition, aluminum is a highly recyclable material, making it an environmentally friendly choice. Recycling aluminum requires only a fraction of the energy required to produce new aluminum from raw materials, which reduces energy consumption and greenhouse gas emissions.

Overall, extruded aluminum has a range of desirable characteristics, including its lightweight yet sturdy nature, high malleability and workability, and corrosion resistance. These characteristics make it an ideal material for a variety of applications, from building facades to automotive parts. Additionally, its recyclability makes it an environmentally friendly choice for manufacturers and consumers alike.
