Define the term - Extrusion
It is a metal working process that produces long lengths of uniform cross sectional area from a metal billet by causing the latter to flow under hydrostatic pressure through a restricted die or opening. It's mainly a hot working process; starting with cast billets and producing wrought sections and tubes in one stage. It has 3 key components container, die ram. A heated cylindrical billet is placed in container and forced out through a steel die by a plunger or ram. Mainly used for manufacturing rods, tubes (rectangular, circular and hollow forms).
