Understanding Aluminium Extrusion

Definition of Aluminium Extrusion

Aluminium extrusion is a process where aluminium alloy material is pushed through a die with a specific cross-sectional profile. This method produces shapes that are used in an extensive array of applications, from automotive parts to building frameworks. Think of it like squeezing toothpaste out of a tube but with aluminium being shaped into precise, custom profiles.

Historical Development

The concept of extrusion dates back to the 18th century, but its application with aluminium became prominent in the early 20th century. The technology has evolved significantly, making aluminium extrusion a crucial process in modern manufacturing.

The Extrusion Process

The process begins with heating the aluminium billet until it becomes malleable. It is then forced through a die under high pressure, resulting in a long piece that takes on the die's shape. This extruded piece is then cooled, stretched, and cut to the required length. The precision and efficiency of this process allow for the creation of complex shapes and designs.
