Aluminium extrusion's endless opportunities
The advantages of aluminium are to a great extent based on their manufacturing method. Extrusion provides unique construction and design possibilities.
The extrusion process starts with ingots of aluminium alloy. We cut these into smaller logs, or billets, and heat them in an induction furnace to the right extrusion temperature.
The heated billet is forced through a die under great pressure, and the finished extrusion is squeezed out of the die like toothpaste from a tube. It is then cooled using air or water.
With the extrusion process, aluminium can be shaped in almost any way desired. This provides unique construction and design possibilities, which is a good foundation for creating products that contribute to sustainable development.
Once cooled, the extrusion is stretched to relieve any stress and to give it the desired straightness. We check surface quality and the dimensions that are important to the function of the profile. It is then cut to a suitable length, or to the length requested by you.
The final strength of the material is controlled through natural or artifical aging.
