Capital Aluminium Extrusions Limited

Aluminium Extrusion is a plastic deformation process of a pre heated aluminium billet which is forced to flow by compression through a steel or ceramic die with an aperture of a smaller cross-sectional area than the original billet.
The extrusion process can be used to produce solid sections, bars, rods from solid billets through flat dies. Tubes and hollow sections can be produced by extrusion through porthole or bridge type dies (for certain alloys).
Seamless tubes and hollows sections must be produced using either hollow billets or solid billets using a piercing press and mandrel system. There are two main methods of aluminium extrusion.
