The aluminum extrusion process is a manufacturing method used to create aluminum profiles with a uniform cross-sectional shape.
The process begins by heating an aluminum billet until it becomes soft and malleable. The billet is then placed inside an extrusion press and pushed through a specially designed steel die using high hydraulic pressure.
As the aluminum passes through the die opening, it forms the desired profile shape. The extruded profile is then cooled, stretched to remove internal stress, and cut into specific lengths.
This process allows manufacturers to produce complex aluminum profile shapes with high dimensional accuracy and excellent surface quality.
