In this study, a shrink fitting process for producing die carring hook of stamping die set was developed through alternative process for sustainable production. Die carring hook is usually manufactured by machining process. Machining process is very common and easy process. However, this process has some disadvantages such as excessive material loss, low productivity, and relatively low mechanical properties. Especially, the excessive material loss and the low productivity are the most serious problems. In order to overcome these problem, the shrink fitting process was applied to manufacture die carring hook for achieving less material loss and higher productivity. In this study, after manufacturing the head ring and body of die carry hook, the two parts was tighten through shrink fitting process. In order to apply the shrink fitting process, the shrink fitting process was analyzed by using FEM. Through FE analysis, heating and cooling process of shrink fitting was analyzed. And after cooling process, the clamping force between head ring and body was predicted to evaluate the quality of die carring hook. The result of FE analysis was verified through experiment. As a result, when the shrink fitting process was applied, not only material utilization but also productivity can be improved approximately 32% and 40%, respectively.
