Abstract
Detail analysis is presented for the influence of elastic deformation on profile wall thickness, the metal flowing and stress load situation of an asymmetry multi-mandrel die. Through the combination of numerical simulation and traditional experimental design, the method on complex section extrusion dies by quantitative prediction of the elastic deformation situation, can improve the accuracy and success rate effectively. In addition, profiles can be extruded stably when the exit velocity fluctuation is under a corresponding range. Under this range, deformation stress caused by uneven metal flowing is under the critical stress, which relates to the thickness to width ratio t/b.
