The second station is called the cupping station. This is where the blank is first reduced. The reduction of the blank should not be any more than 45% of the blanks diameter which will avoid any tearing of the material. Following the second station or cupping station are a series of deep drawing stations. Depending on the press it is common to have up to 12 to 15 stations to form a finished part.
