Aluminium Extrusion Process
At Aludate, we view aluminium extrusion not just as a manufacturing method, but as a precise engineering art. We manage the transformation of high-quality aluminium billets into complex cross-sectional profiles with strict adherence to dimensional tolerances and surface quality. Our extrusion process standards ensure that every profile meets the specific mechanical and aesthetic requirements of your industry.
From Design to Reality: How We Operate
The production cycle within the Aludate ecosystem follows a rigorous technical path designed to maximize durability and efficiency:
- 1. Die Design & Tooling: The process begins with the precise engineering of the extrusion die. Whether for standard shapes or custom aluminium profiles, the tooling is crafted to ensure exact flow dynamics and structural integrity.
- 2. Billet Heating: Premium quality aluminium logs (billets) are heated to optimal temperatures (approx. 450°C - 500°C) to achieve the necessary malleability without compromising the metal's properties.
- 3. High-Pressure Extrusion: The heated aluminium is forced through the die using high-tonnage hydraulic presses. This stage determines the profile's shape, surface finish, and dimensional accuracy.
- 4. Cooling & Stretching: Once extruded, the profiles are cooled evenly and mechanically stretched to straighten the material and relieve internal stresses, ensuring perfect alignment.
- 5. Aging (Heat Treatment): To achieve the required hardness and mechanical strength (e.g., T5, T6 tempers), the profiles undergo a controlled thermal aging process in specialized ovens.
Alloy Selection & Material Quality
The quality of an extruded profile starts with the raw material. Aludate supplies profiles primarily in the 6000 series aluminium alloys (such as 6060, 6063, and 6082), known for their excellent extrudability, corrosion resistance, and surface finish suitability.
Our technical team assists you in selecting the right alloy and temper to match your project’s needs, whether for architectural systems, automotive components, or industrial automation.
Precision & Tolerance Control
In the world of industrial aluminium profiles, precision is everything. Our quality assurance protocols strictly monitor wall thickness, twist, and flatness tolerances according to EN 755 and EN 12020 standards. This meticulous oversight guarantees that Aludate products integrate seamlessly into your assembly lines and construction projects.
