Aluminum extrusion is a manufacturing process in which heated aluminum alloy is forced through a specially designed die to create a continuous profile with a consistent cross-sectional shape.

The extrusion process allows manufacturers to produce complex aluminum profiles efficiently while maintaining a high level of dimensional consistency.

Unlike machining a profile entirely from solid material, extrusion can create the basic cross-sectional geometry first, reducing material waste and machining time for suitable applications.

After extrusion, the profile can be cut to length and undergo additional processes such as:

• CNC milling
• Drilling
• Tapping
• Slot machining
• End machining
• Deburring
• Surface finishing
• Assembly

This makes aluminum extrusion particularly suitable for structural profiles, housings, frames, rails, brackets, heat dissipation components, and other products requiring long or complex cross-sectional geometries.
