How are Aluminium Extrusion Profiles Made?

Aluminium extrusions begin as aluminium ingots that are heated to their?plastic state?in hydraulic presses. The hot aluminium is forced to flow through a preformed die opening,?shaping it into the desired profile. As the aluminium exits the die, it cools and hardens into its final form.

The die opening can be designed with any cross-sectional shape, allowing aluminium extrusions to be customised for specific needs. Common extruded shapes include tubes, angles, channels, ‘I’ beams, and other structural geometries.?By changing the die, unique designs can be produced cost-effectively.
