Engineering Precision & Custom Manufacturing
Zunex Quartz Products Co., Ltd. is situated in Donghai County, Jiangsu Province, China — world-renowned as China's crystal and quartz industrial center. We are a professional production and export-oriented enterprise dedicated to the research, development, precision machining, and distribution of premium fused quartz and experimental quartz glass apparatus.
Our comprehensive production facility specializes in manufacturing high-purity optical quartz glass sheets, synthetic sapphire sheets, furnace quartz tubes, fused silica rods, slotted quartz boats, laboratory quartz beakers, and bespoke experimental glassware. By leveraging direct raw material supply chains and modern fabrication equipment, we deliver high thermal shock resistance, chemical inertness, and exceptional optical transmission across UV, visible, and infrared spectra.
A primary core competency is our quartz laser finishing capability, featuring micro-hole drilling, precision slot grooving, and tight-tolerance contour cutting. We operate under the philosophy of win-win cooperation and total quality assurance, supporting full OEM/ODM processing strictly tailored to engineering drawings and 3D models.
