Abstract
A method and tooling for fabricating a thin plastic plate of large format and of large thickness and including a card of small format and of small thickness that is detachable from the plate. The method, which may be implemented using the tooling, includes operations for making a spotface in a face of the plate to a depth equal to the difference between the large thickness and the small thickness; punching in the spotface zone along a leveling direction facing another face of the plate opposite from the first face, to a leveling stroke (en) equal to the depth of the spotface, in order to bring the bottom of the spotface level with the first face of the plate; and pre-cutting an outline of the card within the leveled zone, in order to make the card detachable.
