Aluminum extrusion is the act of forcing heated aluminum logs or billets, through a pre-cast steel die. This action squeezes the heated aluminium into a predetermined shape, thus creating an aluminum profile.
Aluminum Extrusion Step:
1. Prepare extrusion die
2. Aluminum billet is preheated
3. The billet is transferred to the extrusion press
4. Extruded aluminum profile
5. Sawing to extrusion length
6. Ageing Treatment
7. Surface Treatment
Available Surface finishing processes such as anodizing , painting, powder coating, sandblasting, and wooden grain.
8. Fabrication
Profiles can be punched, drilled, cnc machined, cut, etc. to match your specifications.
For example, the fins on extruded aluminum heatsinks can be cross machined to create a pin design, or screw holes can be drilled into a structural piece.
