Extrusion is a ____________ process that creates and delivers a stream of material for subsequent shaping or forming.

Solution

EXTRUSION IS ON OF THE TYPE OF MANUFACTURING TECHNIQUE TO PRODUCE CONTINUOUS LEANGTHY PROFIL OF DIFFERENT SHAPES IN INDIVIDUAL EXTRUSIONS.

Extrusion is one of the method of shaping material by compressiove force.In extrusion shapes produced by means of only compressive and shear force in stack without any tensile force, which makes high deformation possible with out tearing the materinal.

Types of Extrusion:

1.Direct Extrusion 2.Indirect Extrusion. 3.Hydrostatic Extrusion and 4.Impact Extrusion

Defects in extrusion process:

surface cracking,pipe defects and Internal cracking are the main defects.
