SUNGJIN FO-MA Inc., a global company specializing in cold forging, faced a significant challenge in the prediction of precision forging processes with springback. Precision forging is a process where tight tolerances are a must, and the phenomenon of springback has a significant influence on the final shape of the product. Conventional forging processes are followed by cutting or trimming to achieve the final shape of the desired product. However, in precision forging, the springback phenomenon has to be considered during process design. The company was particularly concerned with the forging process of the intermediate yoke, a critical steering component, where the springback phenomenon is predominant in the region between the two ears.

To tackle this challenge, SUNGJIN FO-MA turned to the elasto-plastic module of AFDEX through the Altair Partner Alliance. The company had realized the importance of FEM simulation of forging processes long back and now wanted to accurately predict the springback phenomenon. The intermediate yoke's forging process was simulated using AFDEX. During the unloading of the punch (5th stage), the two ears came closer towards each other due to springback. This springback amount was predicted and compared with experiments, and it was found that the simulation results matched very well. The use of AFDEX allowed SUNGJIN FO-MA to better design their process, increase productivity, and produce high-quality components.
