In the Metal Stamping industries, there are common styles of Press Lines that parts are formed on - Progressive, Transfer, Tandem. Progressive Press Lines run smaller parts and do not require automation or tooling to move parts from die to die. Transfer Press Lines have 3 Axis Transfer Rails (Mechanical or Servo) where automation tooling (Finger Tooling) is mounted and used to transfer the part from die to die. Transfer Presses have either Mechanical Transfer or Servo Transfer Systems. Mechanical Transfer have a fixed motion relative to the Press Ram timing, where as Servo Transfers motion is not limited to fixed motion, allowing for custom motions of transfer rails to be optimized for maximum throughput. Tandem Line Presses will have multiple Press in a row. In a Tandem Line, there can be between 4 to 7 Presses. The Press tending or part transfer in Tandem lines may have simple 3 Axis Pick and Place Systems or a number of 6 Axis Robots that Load/Unload parts into or out of the presses.
