Introduction
Aluminium extrusion has become a cornerstone of modern manufacturing, offering unparalleled versatility and precision in shaping aluminium into custom profiles. This process, where aluminium is forced through a die to create specific cross-sectional shapes, has revolutionised industries such as construction, automotive, aerospace, and electronics. Aluminium extrusionprovides manufacturers with lightweight, durable, and cost-effective components, catering to an ever-growing demand for innovative solutions in modern manufacturing.
What is Aluminium Extrusion?
Aluminium extrusion is a process where aluminium billets are heated and pushed through a pre-designed die to create long sections of material with uniform cross-sections. These sections can range from simple shapes like rods and tubes to intricate designs customised for specific industrial needs.
The process consists of three main steps:
- Heating the Billet: The aluminium billet is heated to a temperature that makes it malleable but not molten.
- Extruding the Aluminium: The billet is forced through the die using a hydraulic press, forming the desired shape.
- Cooling and Finishing: The extruded aluminium is cooled, cut to the required length, and finished with treatments such as anodising or powder coating.
This technique allows manufacturers to produce complex profiles with high precision, ensuring that components meet exact specifications.
