PPT-Chapter 6 - (Extrusion)

Extrusion is the process by which a blockbillet 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. It should not therefore be construed as a warranty of specific properties of the products described or a warranty for fitness for a particular purpose Classified according to EU Directive 199945EC or further information see our Material Safety Data de wwwecthaendlede ECT Combined DeAiring Extrusion Units in a class of their own Almost a dozen combined deairing extrusion machines have been develo ped by us since 2002 The rapidity of our programme ex pansion has enabled us to incorporate the lat -493 2-4942 -4932-494 2 Numbers of applicable related parts are decided at the time of selecting aluminum extrusions.When selecting related parts, see No. as reference.
