wink envelope dies are available as window dies, profiles and separators with the latest variable geometry. They are suitable for all common magnetic and anvil systems. Variants are also available with clamping or pin bars for use as a feed guide.

Our envelope dies are also impressive because of their extremely high durability and contour accuracy. Using the latest CNC technology not only leads to high dimension accuracy and minimum tolerances, but also enables us to fulfil special requirements - from tear perforations to trimmer and security cuts.
