封边通常被用作冲压作业的最后阶段。它用于改善外观(以创建平滑的边，而不是具有毛刺的剃刀边)，或者用于将一个板金零件附着到另一个板金零件。折边定义为将弯曲或带凸缘的薄板折叠180°或以上。然而，与简单的弯曲和翻边工艺相比，变形机制和工艺是不同的，也更复杂。因此，研究文献中提供的信息很少，而且大多数包边模具都是基于试错设计的。本文给出了在净成形制造工程研究中心(ERC/NSM)用1050铝合金进行的包边实验结果。
Hemming is often used as the last stage of stamping operations. It is used either to improve appearance (to create a smooth edge rather than a razor edge with burrs) or to attach one sheet metal part to another. Hemming is defined as folding of bent or flanged sheet 180° or more. However, the deformation mechanism, and hence the process, is different and more complex than simple bending and flanging process. Therefore, very little information is available in research literature, and most of the hemming dies are designed based on trial and error. This paper gives the results obtained from the hemming experiments that were conducted at the Engineering Research Center for Net Shape Manufacturing (ERC/NSM) by using Aluminum Alloy 1050.
