Orifice Rings for Glass Hot End
Features
95% corundum/99,7% corundum
The orifice ring with oxide ceramic insert for the packaging glass producers has been developed by HENGLI many-many years ago.
More and more glass makers dedicated to LONG-PRODUCTION RUN if producing the same container non-stop.
Several technical solutions as well as economical less or more expensive inserting solution existing on the market.
Application
The clear, added-value of these HENGLI-made solutions is confirmed by many glass makers including all International Groups in Glass Packaging experiencing really a huge savings with a life spam 70-150 days depending on gob-temperature and pulling rate especially for DG/TG.
Very best advantage of these inserts Orifice ring having no decolorization even for flint and extra flint glass at all.
Long-run options: 88% zircon-corundum/95% high-zirconia.
HENGLI-isostatic pressed inserted options either high-alumina-based ceramics with proper machining or developing a new solution with high- alumina-zirconia solutions (pilot project), that will grant even longer life spam, but having relatively low thermal shock- resistance.
