This study shows that SHF provides an effective method to make premium products with complicated shapes or depth. In contrast to conventional methods such as stamping or drawing, SHF could make products with more complicated shapes through on stage forming, and the products also possess high surface quality. This experiment also shows that material selection and local corner radius design are very important, with proper design we could accordingly complete the forming through on stage.

本研究经由实验验证了板材液压成形技术提供了一项有效的方法来高制造具复杂度或具深度之高品质零件，相对於传统冲压或引伸方式，能够一次成形至更复杂造型成品，且制品具有高表面品质，但材料的选择与局部特徵R角设计仍扮演重要关键角色，需搭配设计适当之特徵R角，如此则能够以最具经济与效益的方式一次成形至所需成品。
