Patent ID: 8789404

Claim:
A method of forming a compression limiter from powder metal, comprising the steps of: pressing the powder metal in a longitudinal direction with a movable punch and thereby shaping an outer surface of the compression limiter against an inner die surface of a die cavity; shaping an inner surface of the compression limiter against a core rod disposed in the die cavity while simultaneously shaping the outer surface, a distance between the outer surface and the inner surface of the compression limiter defining a radial direction perpendicular to the longitudinal direction; shaping a retainer projecting from the outer surface of the compression limiter against a side punch disposed in the die cavity while simultaneously shaping the outer surface, the retainer including: a first retention surface having at least a planar portion perpendicular to the radial direction; an undercut surface being disposed radially inwardly from the first retention surface so as to create a corner extending in a direction with at least a component perpendicular to the longitudinal direction; and removing the compression limiter from the die cavity by lowering the die cavity relative to the side punch and moving the compression limiter laterally out of engagement with the side punch relative to the longitudinal direction.
