Densification Point
Functional Range of Motion
The only moving parts on a cutting die are the ejection materials.
As with any moving mechanical or compressible part there is a maximum functional range of motion. Once that range is exceeded the item no longer functions properly which will lead to failure.
This chart shows the maximum functional range of motion in green for each product. Once the functional range is exceeded it enters the yellow densification point where the rubber becomes a solid and can no longer compress. Go beyond this point and the rubber will fail and break apart. For the ejection rubber to work properly it must remain within the green Functional Range of Motion.
