Aluminum Extrusion Process and Extrusion Terminology

Extrusion Defined. Extrusion is defined as the process of shaping material, such as aluminum, by forcing it to flow through a shaped opening in a die. Extruded material emerges as an elongated piece with the same profile as the die opening. To aid in understanding the aluminum extrusion process think about a Play-Doh® Fun Factory and how it works.
