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.
