Introduction: The Importance of Aluminium Profiles
Aluminium is one of the most lightweight, durable, and corrosion-resistant materials used in construction and manufacturing.
From window frames and architectural facades to machine frames and modular assembly lines, aluminium profiles are everywhere in modern industry.
But how are these high-quality aluminium profiles produced?
In this guide, Shanghai Slink Technology, a one-stop aluminium profile supplier, explains the complete aluminium production process, including extrusion, surface treatment, and CNC processing.
1. From Bauxite to Aluminium: The Raw Material Journey
The production of aluminium profiles begins with bauxite, the natural ore used to create aluminium.
Key steps:
- Refining (Bayer Process) – Bauxite → Alumina (Al₂O₃)
- Smelting (Electrolysis) – Alumina → Pure Aluminium
- Casting – Molten aluminium → extrusion billets
2. Aluminium Extrusion: Shaping the Profiles
Aluminium extrusion is the process that gives profiles their precise shape and strength.
Step-by-step extrusion process:
- Billet Heating (450–500°C) – Makes aluminium malleable
- Extrusion Through Die – Creates T-slot aluminium or custom profiles
- Cooling & Stretching – Ensures strength and straightness
- Cutting to Length – Profiles are prepared for surface treatment

3. Surface Treatment: Strength and Aesthetics
To improve durability, corrosion resistance, and appearance, aluminium profiles often undergo:
- Anodizing – Ideal for outdoor and industrial use
- Powder Coating – Adds color and weather resistance
- Polishing/Brushing – Enhances premium appearance
