Orifice Rings for Glass Hot End - Quality Zircon-Mullite from China Suppliers and Factory
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.

Frequently Asked Questions
Q1: What materials are used in HENGLI orifice ring inserts?
HENGLI utilizes 95% corundum and 99.7% corundum inserts. Additionally, long-run options include 88% zircon-corundum and 95% high-zirconia materials.
Q2: What is the typical lifespan of these ceramic inserted orifice rings?
Depending on the gob-temperature and pulling rate (especially for DG/TG), glass makers experience a long service life span ranging from 70 to 150 days.
Q3: Will these inserts cause decolorization in high-quality glass?
No. One of the greatest advantages of these insert orifice rings is that they produce no decolorization at all, even for flint and extra flint glass.
Q4: What is the chemical composition of the Z20-CFP Orifice Ring?
The Z20-CFP contains 67% AL2O3, 20% ZrO, 12% SiO, 0.1% Fe2O3, 0.2% NaO, and 0.1% TiO2.
Q5: What are the physical specifications of the Z20-CFP model?
It features an apparent density of 2.65 g/cm³, a cold crushing strength of 50 N/mm, open porosity of 29%, and thermal expansion of 0.7 at 1000℃.
Q6: Are there new solutions being developed for even longer production runs?
Yes, HENGLI is developing isostatic pressed inserted options with high-alumina-based ceramics as well as a pilot project utilizing high-alumina-zirconia solutions designed to grant even longer service life.
