Extrusion is a process to create objects of a long tube or rod like shape and fixed cross-sectional profile. A material is pushed or drawn through a die of the desired cross-section. Extrusion may be continuous and can be done with the material hot or cold.
The main advantages of this process over other manufacturing processes include its ability to create very complex cross-sections and work materials that are brittle, since only compressive and shear stresses but no tensile stresses involved. It forms finished parts with an excellent surface finish with a set of good die.
Commonly extruded materials include metals, polymers, ceramics, concrete and foods. Everyday examples include copper and plastic pipes, steel and copper wires, French fries, pastas, whip cream decors on cakes, and many rods, bars, tubes, and rails in most households.
