When designing castings, the stresses occurring during operation and machining must be taken into account and used a basis. In addition, some casting materials, such as flake graphite cast iron , are particularly notch-sensitive. Compressive stresses rather than tensile and bending stresses should be applied, especially when using GJL. Notches and changing cross sections should be avoided by means of structural changes wherever possible. For the absorption of bending moments, such as with the wall-mounted support arm in Fig.

Bar Extrusion. Living reference work entry First Online: 25 January How to cite. Synonyms Extrusion ; Extrusion of sections. Introduction Bar extrusion is a process in which a block of metal billet is forced to flow by compression through a tool die opening of a smaller cross-sectional area than that of the original billet. There are two basic types of bar extrusion: direct and indirect. The most important and common method used is the direct extrusion Lange Open image in new window.
