Borosilicate Capillary Tubing and Rods Manufacturer & Manufacturers serving Thailand

Using our advanced vertical redraw towers with real-time continuous laser micrometer monitoring, we maintain outer diameter (OD) and inner diameter (ID) tolerances down to ±0.002 mm (±2 µm) for specialized microfluidic and optical fiber sleeve applications. Standard commercial production tolerances typically range between ±0.01 mm and ±0.03 mm depending on overall wall thickness and aspect ratio.

We provide full Incoterms flexibility including EXW, FOB, CIF (Bangkok/Laem Chabang), and DDP directly to your manufacturing plant in Chonburi, Rayong, Ayutthaya, or Bangkok. Under the China-ASEAN Free Trade Agreement, we supply Form E Certificates of Origin, enabling Thai importers to benefit from preferential tariff rates (often 0% import duty on technical glass tubing).

Yes. Beyond standard score-and-snap cutting, our cold-working and hot-processing workshops offer precision diamond wire dicing, mechanical flat lapping and polishing (surface roughness Ra < 0.5 nm; 40-20 or 20-10 scratch-dig), high-temperature fire-polishing to remove micro-burrs, and custom beveling/chamfering on inner and outer edges to facilitate fluid or fiber insertion.

Borosilicate 3.3 glass offers exceptional thermal shock resistance (up to ~450°C continuous service) and superior hydrolytic/acid resistance at an economical manufacturing cost point, making it the premier choice for fluidics, chemical analysis, and optoelectronics. Quartz glass (fused silica) offers even higher working temperatures (up to 1,100°C–1,200°C) and deep UV transmission below 260 nm (JGS1 down to 185 nm), but requires significantly higher melting temperatures, resulting in higher unit costs.

We support both prototype development and mass-scale recurring batch production. For custom dimensional prototypes, our MOQ starts from as few as 50 to 100 pieces depending on geometry, with typical prototype turnaround completed within 7 to 10 working days. For mass OEM supply, our factory scales to hundreds of thousands of meters per month.
