许多较困难的机加工可以采用连续压印。不过,最大的问题是大多制造广仍然认为压印是一种压花形式,如联邦政府造币厂所使用的模具那样。因此这种技术被认为不过是在高延性金属片的背面压出以往美国总统的头像而已。但是,对于冷镦和冷成形工序中的转移金属方式 Many more difficult machining can use continuous imprinting. However, the biggest problem is that most manufacturing still consider embossing an embossing, as the mold used by the federal government mint. Therefore, this technique is considered as nothing more than stamping out the image of the former U.S. president on the back of highly ductile metal sheets. However, for the cold heading and cold forming process transfer metal mode
