Orifice Rings

Overview

The function of an orifice ring is to control the diameter of a molten glass gob. The expendable refractory part also allows a predetermined number of gobs to pass through its holes in the container glass operation. Pyrotek offers orifice rings for single- and multiple-gob applications in a variety of compositions.

Benefits include:
