company news about What is aluminium extrusion?

Aluminum extrusion is a manufacturing process in which aluminum is shaped into a specific cross-sectional profile by forcing it through a die. The process begins with a cylindrical billet of aluminum that is heated to a specific temperature and then pushed through a die using a hydraulic press. The die is typically made of steel and is designed to give the aluminum the desired cross-sectional shape.

During the extrusion process, the aluminum is forced through the die under high pressure, which causes it to take on the shape of the die opening. The resulting aluminum profile can have a variety of shapes, including solid or hollow tubes, channels, angles, and custom shapes. Once the aluminum has been extruded, it can be cut to the desired length and finished with additional processing such as surface treatment, painting, or anodizing.

Aluminum extrusion is a versatile manufacturing process used to produce a wide range of products, including window frames, door frames, heat sinks, automotive parts, and structural components for buildings and infrastructure. The process offers several advantages over other manufacturing methods, including high dimensional accuracy, low tooling costs, and the ability to produce complex shapes with tight tolerances.
