摘要：A method for making high precision hard film coating on a mold core comprisesthe following steps of: (a) providing a mold jig () and a mold core (); (b) defining a throughhole () of a first inner diameter in the mold jig; (c) forming a rim () of a second inner

diameter on the inner side of the through hole, the second inner diameter being smallerthan the first inner diameter; (d) configuring the mold core into a mold core including abody () of a first external diameter and a top portion () of a second external diameter, thesecond external diameter being smaller than the first external diameter to define ashoulder () between the body and the top portion, the first external diameter beingsubstantially equal to the first inner diameter and larger than the second inner diameter,the second external diameter being substantially equal to or smaller than the secondinner diameter; and (e) coreing the mold core into the through hole of the mold jig fromthe bottom, the shoulder of the mold core engaging with the rim, the upper surface ofthe top portion of the mold core being substantially flush with the upper surface of themold jig, and a groove () being defined between the inner side of the through hole andthe outer side of the top portion of the mold core. A device for performing this methodis also disclosed.
