Engineering Excellence in Fused Quartz Rod Manufacturing
At Zunex Quartz Products Co., Ltd., we utilize high-purity natural silica sand sourced in Donghai County—China's recognized capital of crystal and quartz materials. With modern cold-working CNC machining, precision diamond cutting, hot-flame reshaping, and proprietary laser finishing capabilities, we produce quartz glass rods designed to meet strict international standards for optical, semiconductor, solar photovoltaic, and chemical laboratory applications.
Custom Machining & Laser Grooving
Specialized diamond grinding, precision slotting for semiconductor wafer handling rods, end-face optical polishing (λ/4 flatness, 40/20 scratch-dig), laser hole drilling, and custom flame-bending per technical drawings.
Purity & Thermal Shock Resistance
SiO₂ content ≥ 99.99% with extremely low hydroxyl content options (JGS3). Low coefficient of thermal expansion (5.5 × 10⁻⁷ /°C) ensures thermal shock endurance up to 1100 °C continuous and 1300 °C intermittent operating temperatures.

Frequently Asked Questions for Quartz Glass Rod Procurement
Can you machine quartz rods based on CAD / STEP drawings?
Yes. OEM and ODM custom fabrication is our core capability. We handle CNC lathe profiling, wafer-retention slotting, flame-welded loops, micro-drilling, and customized lengths up to 2000 mm based on your engineering drawings.
What is the difference between fire-polished and optically polished rod ends?
Fire polishing rounds and glazes the quartz surface via oxy-hydrogen flames, providing high mechanical strength and smooth touch at low cost. Optical mechanical polishing delivers flat, parallel end-faces with controlled roughness (Ra < 2 nm) optimal for light guide couplers and laser prisms.
How does Zunex prevent transit breakage for international orders?
We package quartz rods using shock-absorbent multi-layer Pearl cotton (EPE), bubble cushioning, rigid PVC cylindrical core tubes, and heavy-duty export plywood crates. All consignments are fully insured for air and ocean freight.
