Abstract
A method of applying a marking to a part in a stamping die includes moving a component of the stamping die, the component having a mechanical application device secured thereto. A controlled volume of a marking medium flows through the mechanical application device during the moving such that a volume of the marking medium is controlled by the moving of the component during a stamping die operation. In one form, the component is an upper die of the stamping die.
