Extrusion

Extrusion is a manufacturing process where a material, such as metal or plastic, is pushed through a die with a fixed cross-sectional profile. This creates long objects of a consistent shape, like pipes, rods, or wires.

TECHNICAL DEFINITION

Extrusion is a manufacturing process where a material (e.g., metal, plastic, ceramic) is forced under pressure through a die of a desired cross-section, producing continuous lengths of objects with a uniform profile, widely used for pipes, rods, and structural shapes.

BACKGROUND

Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process.
