  • Areas of components that will be folded or hemmed in post-forming operations should be stretched only slightly in the drawing stage so that they have sufficient elastic reserves in the following operations.
    在成型后操作中将被折叠或包边的部件区域应在拉伸阶段仅略微拉伸,以便它们在后续操作中具有足够的弹性储备。
  • Take increased springback into account (e.g. it is twice as high for sheet metal material AIMg0.4Si1.2 as it is for CR3).
