Closed loop shape that is drawn on a flat 2D plane (referred to as a datum) and is used to create 3D objects.. 2D Profiles consist of:. Points. Lines. Circles. 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)..

Extrusion.  is a process used to create objects of a fixed cross-sectional profile. . Direct Extrusion. Indirect Extrusion. Introduction. :. Extrusion is a compression process in which the work metal is forced to flow through a die opening to produce a desired cross-sectional shape. .. As shown in figure (6.1). Figure (6.1) Extrusion process (direct extrusion). 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. Figure 15.1 Schematic illustration of the direct-extrusion process.. Extrusion process:. metal is forced through a shaped die to form a product with reduced but constant x-sec.(F15.1).
