Aluminium Extrusion
Precise engineering art — transforming high-quality billets into complex cross-sectional profiles with strict dimensional tolerances and surface quality.
Overview
Aluminium Extrusion
Aluminium extrusion is not just a manufacturing method, but a precise engineering art. The transformation of high-quality aluminium billets into complex cross-sectional profiles is managed with strict adherence to dimensional tolerances and surface quality. Extrusion process standards ensure that every profile meets the specific mechanical and aesthetic requirements of your industry.
The production cycle follows a rigorous technical path: (1) Die Design & Tooling — precise engineering of the extrusion die for exact flow dynamics and structural integrity; (2) Billet Heating — premium billets heated to optimal temperatures (450°C-500°C) for necessary malleability; (3) High-Pressure Extrusion — heated aluminium forced through the die using high-tonnage hydraulic presses determining shape, surface finish, and dimensional accuracy; (4) Cooling & Stretching — profiles cooled evenly and mechanically stretched for perfect alignment; (5) Aging (Heat Treatment) — controlled thermal aging in specialized ovens for required hardness and mechanical strength (T5, T6 tempers).
The quality of an extruded profile starts with the raw material. Profiles are supplied primarily in 6000 series alloys (6060, 6063, 6082) known for their excellent extrudability, corrosion resistance, and surface finish suitability. Strict quality assurance protocols monitor wall thickness, twist, and flatness tolerances according to EN 755 and EN 12020 standards.
