Abstract:
A method of forming a reseal element through the use of a mold assembly including first and second mold plates, a shell core, a center pin, a center core, and a mold cavity having a shape corresponding to that of the reseal element and collectively defined by the first and second mold plates, the shell and center cores, and the center pin, the method comprising the steps of:(a) injecting a quantity of a moldable material into the mold cavity to form the reseal element;(b) infusing air between the shell core and the center pin into the mold cavity to dislodge the reseal element from the shell core and the center pin;(c) retracting the center core from the reseal element to define a gap therebetween;(d) retracting the second plate from over the reseal element to expose the reseal element;(e) advancing the first plate toward the second plate to remove the reseal element from upon the shell core and the center pin; and wherein step (a) occurs first, and steps (c) and (d) occur prior to step (e).
