PPT-Lecture six Extrusion Process

Introduction Extrusion is a compression process in which the work metal is forced to flow through a die opening to produce a desired crosssectional shape As shown in figure 61 Figure 61 Extrusion process direct extrusion. aluminium. alloy through double-pocket. dies to manufacture a complex profile.

It`s a term used for shaping metals and alloys using localized compressive forces.. Stresses induced > Yield strength. Extrusion is the process by which a block/billet of metal is reduced . in . cross section . by forcing . it to flow through a die . orifice . under . high . pressure.. Extrusion. A round billet is placed in a chamber and forced through a die opening.. Extrusion Blow Molding is a process that can create hollow parts.  There are two different industry segments that use Extrusion Blow Molding, packaging (bottles) and industrial (any parts that are not bottles).. A material is pushed or drawn through a die of the desired cross-section.. Extrusion.  is a process used to create objects of a fixed cross-sectional profile. . Direct Extrusion. Indirect Extrusion. . Analysis . of . extrusion. ANALYSIS OF EXTRUSION. Let us use Figure 7.1 as a reference in discussing some of the parameters in extrusion. The diagram assumes that both billet and . extrudate. are round in cross section. One important parameter is the . Extrusion is a process where raw materials are forced through a cylindrical barrel in order to form, shape and sometimes . cook.. The . principle behind industrial extrusion is similar to that of a domestic meat mincer, however on a much larger scale.. Direct-Extrusion.
