Introduction
The process of extrusion is simply forcing a billet of metal through a shaped die to produce a continuous length of constant section similar to the die profile. Lead was the first metal to be extruded as pipe in the early 19th century. (J.Bramahs patent in 1897) The extrusion of copper really initiated the extrusion process as a high production process
