| Head Retraction |
At the end of the dwell time the head of the machine will retract and begin its ascent to the start position.
First, the hot stamping die lifts away from the substrate while the foil remains on the
surface for a split-second allowing the foil and part resins to
begin to cool and harden.
Then as the die continues to rise, the foil will be peeled away, starting from the edges and working to the middle.
At this point, the adhesion between the substrate and the foil coatings is greater than the bond between the substrate
and the foil coatings is greater that the bond between the release agents in the coatings and the film carrier,
resulting in a virtual complete deposition of the foil coatings.
