Preform design is important for forging process design.
预制坯设计是锻造工艺设计中的重要内容之一。

The recent trend of net shape and near net shape manufacturing requires that forgingpreform design should be optimized to save materials and energy.
净形和近净形制造要求锻造预成形设计不仅要实现产品的形状，而且要实现材料、能耗、锻件质量等目标优化。

This method can realize net shape forging by optimizing preform die shape. Flashless final forging with complete die fill and without folding-over defect can be obtained.
