How the Aluminum Extrusion Process Works?

Aluminum extrusion produces precise profiles through a series of controlled steps.

Die Preparation

Technicians preheat a steel die to about 450°C and load it into the extrusion press. This step prevents thermal shock and helps aluminum flow evenly.

Billet Preheating

Workers heat solid aluminum billets to 400–500°C. The softened metal becomes pliable but does not melt.

Extrusion

A hydraulic ram pushes the hot billet through the die opening. The metal takes on the die’s cross-sectional shape as it exits the press.

Quenching

Operators cool the new profile rapidly with air or water. Fast cooling locks in the metal’s mechanical properties for strength and durability.

Shearing and Cooling

Workers cut the extruded profile into manageable sections, usually several meters long. These pieces cool to room temperature on a runout table.

Stretching

Stretching machines pull the cooled profiles to straighten them and relieve internal stress. This process ensures the finished product remains straight and strong.

Cutting to Final Length

Operators cut profiles to specific lengths, often between 8 and 21 feet, to meet customer requirements. This step prepares extrusions for shipping or further processing.

Finishing Operations

Secondary operations may include:

• Heat treatment to increase strength.
• Machining for holes or slots.
• Surface finishing, such as anodizing or powder coating, for corrosion resistance and appearance.

This process delivers aluminum extrusions with accurate dimensions, strong mechanical properties, and surfaces ready for any application.
