The method includes the following steps in the order recited: inducing a temperature difference between the cone head and the at least one wiper ring; mounting the at least one wiper ring to an underside of the cone head while maintaining the temperature difference; and holding the at least one wiper ring against the underside of the cone head while the temperature difference dissipates.
