Aluminum Extrusion Process
The aluminum extrusion process involves several steps:
1. Billet Preparation: The aluminum alloy is heated to a specific temperature to soften it for easier shaping.
2. Extrusion: The softened billet is placed in a press, where it is forced through a die to create the desired profile.
3. Cooling: The extruded profile is cooled, typically using air or water, to solidify the shape.
4. Stretching: The profile is stretched to eliminate any internal stresses and ensure dimensional accuracy.
5. Cutting: Finally, the extruded lengths are cut to the required sizes for various applications.
