THE EXTRUSION / PRESSING PROCESS
During extrusion, a heated aluminum block (called a billet) is pressed under high pressure through a specially designed die.
This creates the desired profile shape – similar to squeezing toothpaste out of a tube.
Key steps in the process:
- Forming: The aluminum billet is pressed through the die, and the profile continuously exits the press.
- Cooling: Immediately after exiting, the profile is cooled with air or water to stabilize the material structure.
- Straightening (stretching): Removal of internal stresses and ensuring the profile’s straightness.
- Quality control: Precise measurement of functional dimensions and surface inspection.
- Cutting: Profiles are cut to the required length.
THE ROLE OF ALLOYS
- Aluminum alloy EN AW 6060: Excellent corrosion resistance and outstanding surface quality – ideal for applications with high demands on appearance and durability.
- Hardening: After extrusion, alloys can be further strengthened through natural or artificial aging to achieve the final strength.
ADVANTAGES OF ALUMINUM EXTRUSION
- Flexibility: Production of customized profiles according to specific requirements.
- High quality: Precise dimensional control and perfect surface quality throughout the entire process.
- Increased strength: By carefully selecting alloys, the material strength is perfectly matched to the application requirements.
- Sustainability: 100% recyclable – aluminum can be reused without any loss of quality.
