Aluminium extrusion

Our state-of-the-art extrusion facilities enable us to precisely extrude aluminium profiles of various shapes and sizes. With advanced machinery and skilled technicians, we ensure the highest quality and dimensional accuracy in every extruded profile we produce.

  • Billet Preheating

    The process begins with aluminium billets, which are heated to a specific temperature.

  • Extrusion

    The heated billet is then forced through a shaped die, usually by a hydraulic press, to produce the desired profile.

  • Cooling

    This cooling process through water helps to set the shape and properties of the extruded profile.

  • Cutting and Finishing

    The extruded aluminium is cut to the desired length using saws or shears.
