| Abstract: | This paper qualitatively analysis the formation mechanism of shrinkage cavity in plastic shaping by adopting the theory of plastic deformation. The paper discusses the effects of blank shape on metal flow law and finds out the cafuse for forming shrinkage cavity and the method of eliminating it. The topic will be of great values for saving raw materials and improving the quality of products. |
