Aluminium components offer architectural design freedom combined with
high technical performance. The extrusion process provides an ideal
combination of design freedom, precision and cost-effectiveness.
Design possibilities without geometric limitations:The extrusion process is used to manufacture bars, tubes and custom-designed profiles with high dimensional accuracy. This technology enables the cost-effective production of complex geometries:
- Asymmetrical cross-sections
- Significant variations in wall thickness within a single profile
- Open, semi-open and closed geometries
- Solid, semi-hollow and hollow profiles in various geometries
- Hollow profiles with one or more cavities
- Profiles with highly variable height-to-width ratios
This enables the development of functionally integrated solutions that are precisely tailored to customer requirements.
From ingot to profile:Cast aluminium ingots are used as the raw material. These are heated to between 480 and 500 °C and fed into the press’s heated ingot holder. Under high hydraulic pressure, the heated aluminium is forced through the mould grooves of a steel die. This produces aluminium profiles with a defined geometry and consistent quality.
Technical advantages at a glance:- High dimensional and geometric accuracy – even with complex cross-sections
- Excellent surface finish
- Cost-effective production, even for long lengths
For applications involving large-scale structures, such as building façades or building envelopes, profile lengths of up to 13 metres can be produced. This reduces the number of joints, increases stability and simplifies installation.
Conclusion: The extrusion process forms the basis for cost-effective, precise and extremely versatile aluminium profile solutions.
