Division for Borosilicate Glass Tube, Rod, and Glassblowing Articles

Since 2014, we have been at the forefront of manufacturing borosilicate 3.3 glass tubing-both colored and clear-and intricately designed glassblowing creations.

Our state-of-the-art German technology empowers us with an impressive annual production capacity exceeding 150,000 metric tons of glass tubes. This not only positions us as a leading manufacturer in China but also underscores our commitment to precision and quality through continuous process enhancements.

We excel in high-precision secondary processing, producing bore glass and quartz tubes for critical applications in optoelectronics, fiber optics, telecommunications, and the medical field.

Our product portfolio extends to crafting scientific laboratory glassware, heat-resistant tea and coffee sets, glass water pipes, baby feeding bottles, and a variety of bespoke glassblowing products.
