A method for forming a tool for creating a formed component includes providing a forming tool having a core and cavity with respective core and cavity shutoff bands. Core and cavity finished parting planes are determined, wherein the engagement of the core and cavity finished parting planes defines a forming cavity. Rough portions of the core and cavity shutoff bands are removed to define respective rough parting planes. The respective rough parting planes are offset by approximately 130 microns from the respective core and cavity finished parting planes. The core and cavity are semi-finished to relieve stress within the core and cavity. The core and cavity shutoff bands are fine cut so that outer surfaces of the core and cavity shutoff bands are equal to the respective finished parting planes. The engagement between the core and cavity outer surfaces is substantially free of gaps.
