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

Introducing our high-quality Orifice Ring, expertly manufactured in China using premium Zircon-Mullite materials, containing 10-13% ZrO2 and 18-20% ZrOAs a leading factory and supplier, we prioritize rigorous testing methods to ensure the excellence of our products, Our testing process involves a comprehensive assessment of samples across three vertical positions (top, middle, and low) and five horizontal positions (right, mid-right, middle, mid-left, and left). During these tests, we introduce a colored tracer to represent potential glass defects, simulating heterogeneities in the glass structure. Our high-resolution cameras capture detailed observations of the tracer's behavior, culminating in over 150 trials that assess the performance of our patented rotor-tube design, We rank the Orifice Ring's performance on a scale of one to five:, Sharp cord in the Orifice Ring, Nearly sharp cord in the Orifice Ring, Mixed tracer with nearly invisible cord in the Orifice Ring, Choose us as your trusted supplier in China for innovative and reliable Orifice Rings, designed for optimal performance

    Product Detail

    Features

    95% corundum / 99.7% corundum: Developed by HENGLI many years ago, the orifice ring with oxide ceramic insert is specifically designed for packaging glass producers.
    Ideal for glass makers dedicated to LONG-PRODUCTION RUNS when producing the same container non-stop.
    Compatible with several technical and economical inserting solutions available on the market, ranging from standard to premium options.

    Application

    The clear, added-value of these HENGLI-made solutions is confirmed by many glass makers, including all International Groups in Glass Packaging. Users experience significant cost savings with an extended lifespan of 70-150 days, depending on gob-temperature and pulling rate, especially for DG/TG.

    A key advantage of these insert orifice rings is that they cause no decolorization at all, even for flint and extra flint glass.

    Long-run options: 88% zircon-corundum / 95% high-zirconia.

    HENGLI offers isostatic pressed inserted options, featuring either high-alumina-based ceramics with proper machining or a newly developed solution utilizing high-alumina-zirconia solutions (pilot project). This new solution grants an even longer lifespan, though with relatively lower thermal shock resistance.

    Frequently Asked Questions

    Q: What materials are used in HENGLI orifice rings?
    HENGLI orifice rings utilize high-grade materials including 95% corundum / 99.7% corundum. Long-run options also feature 88% zircon-corundum and 95% high-zirconia inserts.
    Q: What is the typical lifespan of these orifice ring inserts?
    Depending on the gob-temperature and pulling rate, these solutions offer an extended lifespan of 70 to 150 days, especially for double gob (DG) and triple gob (TG) setups.
    Q: Do these inserts cause any glass decolorization?
    No. One of the primary advantages of HENGLI's orifice ring inserts is that they cause no decolorization at all, making them suitable even for flint and extra flint glass production.
    Q: What is the chemical composition of the Z20-CFP orifice ring?
    The Z20-CFP model consists of 67% Al₂O₃, 20% ZrO₂, 12% SiO₂, 0.1% Fe₂O₃, 0.2% Na₂O, and 0.1% TiO₂.
    Q: What are the physical properties of the Z20-CFP model?
    It features an apparent density of 2.65 g/cm³, a cold crushing strength of 50 N/mm², an open porosity of 29%, and a thermal expansion rate of 0.7 at 1000℃.
    Q: What new developments is HENGLI working on for longer runs?
    HENGLI is developing a new pilot project solution utilizing high-alumina-zirconia materials. This is designed to grant an even longer lifespan, despite having relatively lower thermal shock resistance.
