Extrusion is the process of deforming a material to give it specific shapes by exerting pressure through a piston rod or punch on the material placed in a container or die. Products obtained by extrusion are characterized by a smooth surface and precise dimensions.
This process is considered to be the most economical way of processing low-plasticity steel. Extrusion is used to produce bars and holes of complex shapes. It is also the primary technique for producing tubes, sections and machine components.
