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