components when setting up the press for a new product. Other universally
used exchange tooling components remain in the holding
sleeves. The exchange tooling include mainly pressure plates, pressure
pins, spring elements and guide sleeves. For the structural design of
active and exchange components of die sets, please refer to the VDI

The die holders hold both the active and exchange tooling components.
Their function is to ensure that the lower and upper die operate
as on-center as possible in relation to each other. The number of stations,
the distance between stations and the holder sizes are generally
grouped together in standardized series. Table 6.7.1 illustrates a modu-
