Aluminum profiles are primarily produced using a manufacturing process called aluminum extrusion.
The process begins with an aluminum alloy billet that is heated to around 400–500°C, making it soft enough to be shaped. The heated billet is then forced through a precision steel die using a powerful hydraulic press. As the aluminum passes through the die opening, it takes on the exact cross-sectional shape of the mold.
After extrusion, the profile is cooled, stretched to remove internal stress, and cut into standard lengths. Depending on the application, additional processes such as anodizing, powder coating, machining, or drilling may be applied.
This manufacturing method allows aluminum profiles to achieve high dimensional accuracy, complex shapes, and consistent quality, making them highly suitable for industrial and architectural applications.
