Fused Silica Rod Suppliers & Exporters Serving the Hat Yai Market

For urgent prototypes, replacement quartz rods, and custom laboratory pieces, we dispatch via direct international air express (DHL, FedEx, UPS) to Hat Yai International Airport (HDY) with typical customs clearance and door-to-door transit times of 3 to 5 business days. For bulk production runs and commercial containers, freight ships through Lianyungang/Shanghai ports directly to Port of Songkhla or via Bangkok (Laem Chabang) with an ocean transit time of 10 to 14 days, followed by bonded road transport into Hat Yai or the Sadao border industrial estate.

Yes. Many advanced manufacturing operations in Songkhla operate under Thailand Board of Investment (BOI) promotion privileges or reside within Free Trade Zones. Zunex Quartz regularly provides complete export documentation packages — including standard Commercial Invoices, Packing Lists with precise Harmonized System (HS) Codes (e.g., HS 7002.20 for quartz rods, 7002.31 for quartz tubes), and Form E Certificates of Origin under the ASEAN-China Free Trade Agreement (ACFTA), allowing qualified Thai importers to claim 0% or substantially reduced customs tariffs.

Slender quartz rods (OD 1 mm to 10 mm) are extremely sensitive to harmonic bending shocks. We employ a rigorous five-stage packaging protocol: First, rods are bundled in protective shrink sleeves with vapor-corrosion and anti-static liners. Second, bundles are seated in custom-routed, shock-absorbing high-density Expanded Polyethylene (EPE) foam channels that prevent flexure. Third, the foam core is housed inside rigid inner cartons. Finally, the assembly is anchored in heavy-duty, fumigated ISPM-15 plywood wooden crates lined with moisture barriers to resist Southern Thailand’s high relative humidity during maritime transport.

The decision hinges on the primary UV wavelength and ozone generation requirements:

• JGS1 (Synthetic Fused Silica): Mandatory if you are utilizing 185 nm deep-UV for total organic carbon (TOC) reduction or ozone generation, or if your system utilizes high-intensity pulsed UV lasers where solarization resistance is required.
• JGS2 (Standard Fused Quartz): The most cost-efficient choice for conventional 254 nm germicidal disinfection loops common in municipal effluent systems, shrimp processing plants, and food packaging lines across Songkhla. It delivers >90% transmission at 254 nm while reducing raw material procurement costs by 30% to 50% relative to synthetic silica.

Yes, custom fabrication to drawing represents our primary business. We process standard STEP, DWG, DXF, and dimensioned PDF engineering drawings. Our CNC cold processing and laser micro-machining capabilities include centerless OD grinding, precision end-face optical polishing (surface roughness Ra < 0.2 nm), laser slotting, step-down diameter turning, blind-hole drilling, and fire-polishing to achieve maximum mechanical bend strength.

For standard draw rods, we typically hold outside diameter (OD) tolerances of ±0.1 mm to ±0.2 mm. However, for precision applications such as optoelectronic collimators, laser cavities, or semiconductor carriers, we employ precision centerless grinding and optical polishing to achieve tight tolerances down to ±0.01 mm with circularity < 0.005 mm and straightness ≤ 0.1 mm per meter.

Fused quartz exhibits near-total chemical inertness to virtually all inorganic and organic acids — including concentrated sulfuric acid, nitric acid, hydrochloric acid, and formic acid commonly deployed in rubber coagulation and testing — even at elevated operating temperatures up to several hundred degrees Celsius. The only exceptions are hydrofluoric acid (HF), which rapidly dissolves SiO₂, and concentrated phosphoric acid at temperatures exceeding 150 °C.

We actively support academic and industrial innovation. We maintain an MOQ of just 1 to 5 pieces for customized laboratory instruments, specialized quartz reactor vessels, and optical test rods intended for university R&D or pilot testing. Once prototype parameters are validated, our production facilities scale seamlessly to high-volume commercial batch runs.
