Engineering High-Precision Quartz Solutions for Global Industry
Zunex Quartz Products Co., Ltd. is located in Donghai County, Jiangsu Province — universally recognized as China's crystal and quartz manufacturing capital. We are an integrated enterprise specialized in the professional R&D, precision manufacturing, and international export of experimental quartz glass products and high-grade industrial quartzware.
Our state-of-the-art facility develops and fabricates premium optical quartz glass sheets, sapphire sheets, high-temperature quartz tubes, quartz rods, semiconductor quartz boats, beakers, and customized laboratory instruments. We pride ourselves on advanced quartz laser finishing capabilities, including micrometer-grade laser drilling, fine-pitch grooving, and clean edge-cutting without thermal micro-fractures.
Custom Fabrication to Your Drawing: We strictly operate under win-win principles, welcoming custom OEM/ODM manufacturing based on CAD, PDF, DWG, or STEP drawings. Our engineering team reviews technical specifications, tolerances, and thermal demands to ensure 100% precision fit.
Serving critical global industries, our products are widely adopted in semiconductor wafer handling, electronic information systems, solar photovoltaics (PV), infrared thermal processing, aerospace optics, chemical engineering, and major scientific research laboratories.
