China Suppliers Orifice Rings for Glass Hot End - High Quality Zircon-Mullite Factory Products

Discover our high-quality Orifice Ring manufactured using premium Zircon-Mullite materials, featuring 10-13% ZrO2 and 18-20% ZrO2 content. As a leading supplier and factory in China, we prioritize rigorous testing to ensure optimal performance. Our testing methodology involves evaluating samples in three vertical positions (top, middle, and low) and five horizontal positions (right, mid-right, middle, mid-left, and left). Each area is assessed with a colored tracer that represents potential glass defects, highlighting any heterogeneities in the glass structure. Our high-resolution cameras capture the behavior of the tracers during over 150 trials, allowing us to establish a performance ranking for the patented rotor-tube design. The results are categorized from one to five, ranging from a sharp cord in the Orifice Ring to nearly sharp and mixed tracer visibility. Trust our China-based factory for innovative and reliable glass solutions.

    Product Detail

    Features

    Material Composition
    95% corundum / 99.7% corundum
    Established Development

    The orifice ring with oxide ceramic insert for packaging glass producers was developed by HENGLI many years ago, establishing a proven track record in the industry.

    Production Efficiency

    Designed specifically to support glass makers dedicated to LONG-PRODUCTION RUNS, enabling continuous, non-stop container manufacturing.

    Several technical solutions, as well as economical options ranging from standard to premium inserting solutions, currently exist 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. Users experience substantial savings with a lifespan of 70 to 150 days, depending on gob-temperature and pulling rate, especially for DG/TG operations.

    Key Advantage
    The primary benefit of these insert orifice rings is that they cause absolutely no decolorization, even for flint and extra flint glass.
    Long-Run Options
    • 88% zircon-corundum
    • 95% high-zirconia
    Advanced Formulations

    HENGLI offers isostatic pressed inserted options using either high-alumina-based ceramics with precise machining, or newly developed high-alumina-zirconia solutions (pilot project) designed to grant an even longer lifespan, though with relatively lower thermal shock resistance.

    Frequently Asked Questions

    Q: What materials are used in the HENGLI orifice ring inserts?
    The standard inserts are made of 95% corundum or 99.7% corundum. Long-run applications also utilize options with 88% zircon-corundum or 95% high-zirconia.
    Q: What is the typical lifespan of these orifice ring solutions?
    Depending on the gob-temperature and pulling rate, particularly for DG/TG, users experience a lifespan of 70 to 150 days.
    Q: Will the orifice ring inserts cause decolorization in flint glass?
    No. One of the greatest advantages of these insert orifice rings is that they cause absolutely no decolorization, even for flint and extra flint glass.
    Q: What is the chemical composition of the Z20-CFP orifice ring?
    The chemical makeup consists of 67% AL2O3, 20% ZrO, 12% SiO, 0.1% Fe2O3, 0.2% NaO, and 0.1% TiO2.
    Q: What are the key physical properties of the Z20-CFP model?
    It features an apparent density of 2.65 g/cm³, a cold crushing strength of 50 N/mm, an open porosity of 29%, and a thermal expansion value of 0.7 at 1000℃.
    Q: What new solutions is HENGLI developing for extended production runs?
    HENGLI is currently running a pilot project developing new high-alumina-zirconia solutions alongside high-alumina-based ceramics, aimed at granting an even longer lifespan.
