Extrusion - Wikipedia

Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections, and to work materials that are brittle, because the material only encounters compressive and shear stresses.

Cold Extrusion of Steel: Part One :: Total Materia Article

Extrusion, though one of the most important manufacturing processes today, is a relatively young metalworking process. The cold extrusion process involves forcing a billet of material through a die at room or slightly elevated temperatures, producing a continuous product of constant cross-section.
