METHOD OF MANUFACTURING A PIN FOR A MOLD FOR A DIE CASTING PROCESS

A method of manufacturing a pin(46) for a mold(28) includes forming the pin(46) to include a substantially uniform initial hardness throughout the entire structure of the formed pin(46). The formed pin(46) is then processed with a hardening process, such that the processed pin(46) exhibits a hardness defining a hardness gradient that gradually increases from the initial hardness at a central interior region(56) of the pin(46) to an increased surface hardness at an exterior surface(60) of the pin(46). After processing the pin(46) with the hardening process, a coating(64) maybe deposited onto the exterior surface(60) of the pin(46) with a physical vapor deposition process. The coating(64) exhibits a hardness that is greater than the hardness of the increased surface hardness of the exterior surface(60) of the pin(46). The pin(46) may include, for example, a core pin, a squeeze pin, or an ejector pin.
