Surface defects in sheet metal stamping AutoForm

Surface defects is an important issue in sheet metal stamping as the stamping process affects surface appearance and thus influences surface quality. A great amount of time is therefore spent during the product development process on the optimization of surface Experimental Assessment of High Temperature Formability Mar 27, 2012· Bending behavior occurs in the hot press forming process, resulting in many cases of failure during forming. To address the problem of cracking and improve the formability and mechanical properties of boron steel sheets in the bending process, an experiment has been carried out by using a spring compound bending die.WO2013157063A1 Method for drawing forming limit And, in the high strength steel sheet showing the cracking behavior as described above, when the occurrence of cracking is predicted using the conventional FLD, even when it is predicted that no cracking occurs, cracking occurs in the press forming. It was found that the amount of bending deformation was large at the site.
