Neck ring and method of making for a glass container forming machine |
摘要 |
A neck ring for molding a glass container neck finish that includes at least one closure attachment feature. The neck ring includes two semi-annular bi-metal neck ring halves, each consisting essentially of a neck ring insert of wear-resistant metal construction, and a neck ring body of heat-conductive metal construction different from said wear-resistant metal construction and formed around said neck ring insert so as to embed it in said neck ring body. Each of said neck ring halves has a glass-contacting cavity face that includes a first surface portion formed by said inserts for molding the at least one closure attachment feature on the neck finish, and a second surface portion formed by said bodies for molding portions of the neck finish excluding the at least one closure attachment feature.
