MARCH 20238PANORAMATHE EVOLUTION OF ALUMINIUM EXTRUSION PROCESSAluminium extrusion process has undergone tremendous technological advances, which have helped manufacturers in the production of lightweight & economical products such as cans, bottles & food packaging. In order to meet the needs of customers today & for years to come, aluminium is extruded through several different operations including punching, coining as well as drawing. The evolution of aluminium extrusion process has been in line with technological innovation. The evolution of aluminium extrusion process started in the 1870s with the first heat treatment of aluminium. It soon became apparent that this was not a suitable material for structural purposes, but its flexibility and strength were found attractive for applications such as bottle tops, buttons and curtain rings. It was not until that DuPont introduced an extruded product whose features were unique among other alloy castings: it possessed excellent formability and could be processed with almost any type of die head or cutter. DuPont introduced the first aluminium extrusion in 1926. This product changed the course of material history forever,
