Platen Die Cutting

Mechanical Action

Die board holding the arranged steel rules is mounted on the upper platen, while the substrate sheet is positioned on the lower platen or counter plate. As the platens come together, the cutting rules penetrate the board, while the creasing rules compress it to form the fold lines. Ejection rubber mounted alongside the rules compresses during the stroke and then expands to push the cut sheet off the die as the platens separate.

This reciprocating action must be perfectly timed to avoid sheet tearing and ensure that the finished blanks are released cleanly without sticking to the steel rules.

Process Efficiency

Precise control over the pressure and alignment is required to ensure that the die cuts cleanly without damaging the steel rules. Modern platen presses feature automatic blanking systems that separate the finished cartons from the waste skeleton in-line. This automation reduces manual labor and speeds up the finishing process for large-volume packaging runs.
