Thermal deep-drawing is a main processing technology which is used to plastic forming for magnesium alloy sheet. Combined with the research status, several deep drawing methods were introduced in detail in this paper, including indirect heating deep drawing, direct heating deep drawing, differential temperature deep drawing, warm hydraulic deep drawing, warm deep drawing with solid particles, warm deep drawing with segmental blank-holder, pre-forming warm deep drawing. Finally, the development trend and burning questions of magnesium alloy thermal forming technology were predicted.

Multi-stage deep drawing process for rectangular cups with extreme aspect ratio using finite element analysis is performed. The process is mainly consists of four forming stages including blanking, drawing, ironing and trimming. However, main deformation of the rectangular cup is completed during the drawing-ironing procedure. Tool design and blank modification for the multi-stage deep drawing process are presented. To consider the deep drawing and the ironing operations, the multi-stage deep drawing process is applied to obtain the rectangular cup by using each numerical simulation models from first to fifth drawing. Based on the design results of the initial blank, the multi-stage deep drawing process is performed, but it is shown that severe earing phenomenon is occurred at the upper flange part. To solve the severe deformation at the upper flange due to normal anisotropy of the used sheet material, initial blank modification is carried out. The simulation results for the rectangular cup are compared with the final configuration before and after the modification of the blank shape. The predicted result is confirmed that the modified blank shape not only improve the quality of a deep-drawn product but also reduce the cost of production.
