What is the purpose of extrusion in manufacturing?

The purpose of extrusion in manufacturing is to push metal through a die to create desired shapes. This process allows manufacturers to produce complex cross-sectional profiles that would be difficult or impossible to create through other methods. During extrusion, the material, often heated or softened, is forced through a specially designed die, resulting in a continuous length of material with a uniform cross-section. This allows for efficient mass production and can easily accommodate variations in lengths according to requirements.

Extrusion is particularly valuable in creating products like pipes, tubes, and various other structural components used in construction, automotive, and aerospace industries. The ability to produce long lengths of consistent shapes not only enhances efficiency but also reduces waste, making it a key process in modern manufacturing.
