Dynaform simulation and analysis on the edge forming of can lid

As the development of deep-processing of aquatic food, the increasing yields of canned aquatic products require a large demand of can making machinery. Edge forming of can lid is one of the key processes in the can-making procedure. To overcome the problems including high cost, high rejection rate, and low production efficiency, edge forming by stamping die was utilized. The stamping die is designed in this study, and the edge forming was simulated with spring back analysis. The quality of lid edge was predicted and the design of stamping die was verified.
