Engineering Excellence

Precision Engineered Fused Quartz Rods

Lianyungang Zelvo Quartz Products Co., Ltd. produces ultra-pure fused quartz rods manufactured from premium Donghai natural quartz crystal sand. Operating continuously at up to 1100 °C (1300 °C peak), our quartz rods provide superior thermal shock stability, negligible thermal expansion, and exceptional optical clarity across ultraviolet, visible, and infrared spectra.

Whether you require optically polished light guides for medical aesthetic devices, precision-slotted carrier rods for semiconductor quartz boats, or chemical-resistant stirring rods, our workshop delivers custom tolerances down to ±0.02 mm.

Technical Q&A

Frequently Asked Questions by Overseas Buyers

What purity grades are available for your quartz rods?
We offer standard high-purity clear fused quartz (99.99% SiO2) for chemical and thermal furnace applications, as well as synthetic fused silica with OH levels under 5 ppm or tailored for deep UV transmission (JGS1, JGS2, JGS3). Material test reports (MTR) can be provided upon request.
What is your minimum order quantity (MOQ) and sample lead time?
Our MOQ starts from just 1 piece for custom prototypes and evaluation orders. Standard stocked sizes ship within 24–48 hours, while custom machined or slotted quartz rods typically take 5–10 business days depending on design complexity.
How do you ensure safe international delivery of fragile quartz glass rods?
Every single rod is wrapped in shock-absorbing EPE foam, individually tubed if required, and packed inside heavy-duty multi-layer cartons or reinforced export wooden crates. We guarantee 100% damage-free delivery under express (DHL/FedEx/UPS), air freight, or ocean shipping.
Can you manufacture according to CAD drawings or 3D models?
Yes. We accept PDF, DWG, DXF, STEP, and IGES file formats. Our engineering team reviews tolerances, wall clearances, and thermal constraints, providing feedback within 2 hours during normal business hours.
