Abstract
A guide-ring comprises a graphite body and a mechanically attached insert, preferable made of metal. The insert and body form a guide ring supporting a split neck-ring used during glass container manufacturing. The graphite body avoids the need for separate lubrication while being sufficiently strong enough to enable mechanical attachment of the insert. The combination provides the structural integrity needed to resist damage during glass container manufacturing operations and the thermal properties needed to contact hot glass gobs.
