Maximize soot deposition yield with micron precision. We provide factory-direct OVD/VAD/MCVD burner parts and deposition torch consumables that match original OEM quality at a fraction of the cost. Seamlessly swap high-wear burner nozzles replacement parts for stable laminar flames and massive budget savings.
4 standard OVD torch components ready to ship. 100% OEM drop-in compatibility—no MFC or hardware recalibration needed.
Custom CNC turn-mill MCVD heating nozzles, VAD components, and gas pathways in 316L SS or copper. Strict NDA protection.
Founded in 2004, our parent factory is a premier precision metal machining specialist. Backed by over two decades of technical expertise (read our material science guide) and an advanced manufacturing fleet, we produce high-tolerance components that meet strict global industrial standards.
Leveraging this strong mechanical foundation, ovdparts.com focuses entirely on the optical fiber preform burner sector. We are dedicated to providing global optical fiber manufacturers with premium, field-validated replacements that perfectly match OEM quality at a fraction of the cost.
In optical fiber preform manufacturing, even a $0.01text{ mm}$ eccentricity in the gas distribution layers can alter the flame geometry. This imbalance disrupts the high-temperature hydrolysis of $SiCl_4$ and $GeCl_4$, leading to uneven soot deposition density and compromised refractive index profiles in the final fiber core.
Backed by our advanced Turn-Mill CNC Machining Centers, we fabricate our burner heads and multi-channel gas bodies in a single setup. This ensures perfect coaxial alignment across all concentric gas rings, delivering an exceptionally stable, uniform flame for your deposition process.

Clogged or unevenly discharging micro-holes are a major cause of premature soot buildup and turbulent gas mixing. Any microscopic burr left inside the nozzle can cause chemical gases to swirl, creating local cold spots on the target mandrel.
We utilize specialized micro-drilling techniques combined with proprietary precision deburring and chemical polishing processes. Every single micro-hole undergoes strict optical projection inspection to ensure a smooth interior wall, optimal flow dynamics, and significantly reduced cleaning intervals for your maintenance team.

OVD and VAD burners operate in harsh environments featuring both extreme temperatures and highly corrosive chlorine-byproduct environments.
We primarily utilize high-purity 316L Stainless Steel, Premium Brass/Copper alloys, and specialized Quartz materials based on your specific equipment requirements. For metal components, we apply advanced surface treatments (such as hard anodization or customized anti-corrosion coatings) to maximize resistance to chemical erosion, ensuring a longer consumable lifespan and fewer tracking errors during long deposition cycles.
See our Material Science & Reverse Engineering Guide for a detailed breakdown of 316L SS vs. Copper vs. Quartz alloy selection for specific deposition setups.
Yes. Our 4 standard OVD/VAD burner components are engineered as direct, drop-in replacements for the industry’s most widely used standard preform deposition setups. They match the original physical dimensions, thread sizes, and gas port configurations perfectly. You can replace your worn-out OEM nozzles seamlessly without modifying your existing gas mass flow controller (MFC) calibrations or burner carriage hardware.

Absolutely. We know that in a multi-layer torch, the outermost nozzle or the internal sealing gaskets often wear out faster than the heavy main inlet body.
We support component-level ordering for all our exploded-view parts. You can purchase just the replacement gas distribution plates, specific nozzle cones, or custom sealing rings. This modular supply approach helps fiber manufacturers cut down on consumable costs by up to 40% compared to buying full assemblies every time.

Yes, custom fabrication of complex, multi-channel thermal components is our core strength. Whether you need a customized VAD axial deposition torch or a specialized MCVD internal/external heating burner, we can machine it precisely to your technical drawings.
IP Protection is our strict policy: Before you share any STEP, CAD, or PDF drawings with us, we are fully prepared to sign a formal Non-Disclosure Agreement (NDA). Your custom designs will be kept strictly confidential, restricted to our dedicated engineering team, and never used for any other client.

ovdparts.com is a specialized, dedicated division of Zhongshan SKY CNC Manufacture Co., Ltd. Established in 2004, we are a premier precision metal machining factory based in China, with over 22 years of deep expertise in custom, high-tolerance CNC turn-mill machining.
While our parent corporate website at sky-cnc.com showcases our broad manufacturing infrastructure and diverse industrial portfolio, this platform was created with a singular focus: to provide the global optical fiber industry with factory-direct, ultra-precision deposition burner components and consumables.
Our precision-engineered OVD and VAD burner parts are already fully integrated and actively running on the high-intensity production lines of China’s top-tier, global optical fiber giants.
Our established corporate track record includes supplying industry leaders such as YOFC (Yangtze Optical Fibre and Cable), Hengtong Optic-Electric, ZTT (Zhongtian Technology), Futong Group, Yongding Stock, Tongding Interconnection, and SDG Information. This widespread adoption by market leaders proves that our components successfully meet the most stringent manufacturing standards in the global fiber optic industry.
We bridge the gap between world-class precision and manufacturing economy through two distinct advantages:
Battle-Tested OEM Quality: The ultimate proof of our quality is field validation. Our burner parts have passed long-term, rigorous operational testing on the production equipment of top-tier fiber manufacturers. We achieve identical concentricity, micro-hole accuracy, and gas flow stability compared to the original parts, ensuring zero compromise on your soot deposition efficiency.
Direct Factory Pricing: Buying from original equipment OEMs usually comes with an immense brand markup. By sourcing directly from our precision machining facility in China, you bypass all intermediaries and OEM premiums, allowing you to secure premium-tier replacement parts at a price significantly lower than the OEM original, drastically lowering your cleanroom’s annual consumable budget.
