Cole创造了一种单行程深拉伸的巧妙方法。该方法是依靠套筒式模具实现的。近来,该工艺方案又有了发展,连续拉伸由3个工步增加到5个工步。其工作原理如图所示。

Cole has created a clever way to stretch deep within a single trip. This method relies on a sleeve mold. Recently, the process has been the development of programs, continuous stretching from 3 steps to 5 steps. Its working principle as shown.
