During deposition, rapid thermal cycling at the boule ends can lead to catastrophic preform cracking and uneven taper geometry. Our auxiliary tail burner eliminates thermal gradients by delivering an ultra-uniform auxiliary flame pattern and steady process gas dispersion across its precision-machined multi-orifice faceplate.

Key Features & Engineering Highlights

• Dual-Inlet Pressure Equalization: Designed with dual symmetrically placed gas inlets to balance internal chamber static pressure, ensuring identical gas velocity across every single micro-orifice along the entire manifold length.
• Precision Multi-Orifice Micro-Drilling: Staggered linear orifice arrays produce a coherent, laminar flame/gas curtain that prevents turbulence, flame flickering, and uneven soot deposition.
• Robust High-Temperature Welded Construction: Fully welded sealed body designed to withstand harsh cleanroom deposition lathe environments, radiation heat from 1600°C+ silica reaction zones, and acidic chloride gas exposure ($\text{SiCl}_4 / \text{GeCl}_4$).
• Boule Stress Relief & Yield Optimization: Maintains precise end-taper thermal profiles, drastically lowering preform tail cracking rates and improving overall rod yield.
• Direct OEM Drop-In Compatibility: Sized and configured to replace standard auxiliary burners and gas distribution rails on legacy and modern OVD deposition lathes without piping modifications.

Technical Features & Engineering Advantages

🔬 Dual-Alloy Hybrid Engineering

Unlike standard single-metal burners, the OVD-NOZ-03 leverages two distinct metals to handle different physical stresses on your fiber optic equipment components:

• Flame-Facing Nozzle Head (Titanium Alloy): The high-heat front face is crafted from premium titanium alloy, providing absolute resistance to flame deformation and chemical corrosion caused by gaseous halides like silicon tetrachloride (SiCl₄) and germanium tetrachloride (GeCl₄).

• Base Manifold (Aluminum Alloy): The body is CNC-machined from high-grade anodized aluminum alloy. Its high thermal conductivity allows the burner to dissipate residual heat rapidly, stabilizing the process gases before they reach the flame.

💨 Turbulence-Free Laminar Flow

Every internal gas pathway is machined via multi-axis CNC turn-mill centers in a single setup to eliminate alignment errors. This ultra-precise structural accuracy prevents internal gas turbulence and back-diffusion, ensuring a perfectly concentric, stable laminar flame profile for high-density soot deposition.

⚖️ Lightweight Design with Secure Mounting

The integration of an aluminum alloy base drastically reduces the overall weight of the burner assembly without sacrificing structural integrity.

• Reduced Equipment Wear: The lightweight design minimizes the mechanical load on your deposition lathe’s automated motion arms, reducing long-term equipment wear and tear.

Product Specifications & Material Index

Every unit undergoes a rigid quality control protocol in our testing facilities to ensure seamless, drop-in compatibility with industrial setups.

Inventory Notice & Ordering Information

• • Limited Batch Availability: Due to the specialized nature of the OVD-NOZ-03, we fabricate this model in limited, high-purity production runs. We currently have a small quantity in stock and ready for immediate shipment via international express air freight (DHL/FedEx/UPS).

  • On-Demand Customization & NDA Protection: If your optical fiber manufacturing line requires custom port sizes, alternative mounting configurations, or specific channel counts, we can custom-machine components to your exact drawings. All custom OEM/ODM development is handled under strict Non-Disclosure Agreements (NDA) to protect your IP.

Optimize your upfront procurement budget without compromising on structural accuracy with our premium aluminum alloy OVD parts. Engineered as a highly economical alternative to premium titanium setups, these CNC-machined components are designed to deliver reliable performance in standard optical fiber preform manufacturing systems.

While aluminum components offer a shorter operational lifespan under intense chemical corrosion compared to our premium titanium lineup, they represent the ultimate budget-friendly solution for short-run R&D, pilot lines, or facilities looking to maximize immediate cash flow and lower replacement costs.

The Aluminum Advantage: Balanced Economy & Thermal Control

💰 Maximum Cost-Efficiency & Budget Savings

For facilities running frequent preventative maintenance schedules or operating specialized research setups, upfront part costs are a critical metric. Our aluminum alloy OVD burner components allow you to secure precision-machined replacement parts at a fraction of the cost of both titanium equivalents and OEM branded spares.

❄️ Superior Thermal Dissipation

Aluminum possesses exceptionally high thermal conductivity. During intense soot deposition runs, these aluminum OVD burner parts rapidly conduct heat away from the flame-facing nozzle head. This rapid cooling keeps the nozzle body temperature low, effectively preventing process gases like silicon tetrachloride ($SiCl_4$) and germanium tetrachloride ($GeCl_4$) from pre-reacting inside the gas channels.

🎯 High-Precision CNC Flow Dynamics

Despite their economical pricing, we make zero compromises on machining accuracy. Every aluminum component is fully machined on multi-axis CNC turn-mill centers to single-digit micron tolerances. This ensures a perfectly concentric, stable laminar flame profile to secure consistent soot preform density.

Product Specifications & Material Index

Every aluminum component undergoes strict dimensional inspection and high-purity anodization to enhance surface hardness and prevent superficial corrosion.

The Titanium Alloy Advantage: Built for Extreme Cleanroom Demands

🔥 Outstanding Heat Resistance & Thermal Stability

Soot deposition burners operate under intense thermal stress. Our premium titanium alloy construction withstands extreme high-temperature cycles without thermal warping, micro-cracking, or dimensional distortion. This guarantees that your gas discharge channels maintain their single-digit micron precision under continuous operation.

⏳ Drastically Extended Service Life

The continuous flow of carrier gases and halides—such as silicon tetrachloride (SiCl₄) and germanium tetrachloride (GeCl₄)—creates a highly corrosive environment that quickly degrades lesser metals. Titanium alloy forms a highly stable, microscopic oxide passive layer, preventing corrosion and eliminating premature nozzle erosion to deliver an unmatched service life.
