A Strategic Manufacturing Hub in China's Quartz Capital
VEZLO Quartz Products Co., Ltd. is located in Donghai County, Jiangsu Province—internationally recognized as "China's Quartz Center." Spanning an area of 50 mu with fixed assets surpassing 10 million RMB, our integrated manufacturing plant is dedicated to the research, development, and high-precision fabrication of premium fused quartz glass products and quartz pipes.
Our comprehensive production serves mission-critical applications across electric light sources, UV disinfection, chemical transmission pipelines, optical communications, industrial heating, and semiconductor wafer fabrication. With deep vertical integration, our product lines range from raw optical materials to custom-engineered quartz components manufactured strictly to engineering drawings.
Verified Enterprise Performance
Advanced Engineering & High-Purity Capabilities
Direct factory production backed by stringent quality verification and continuous technological investment.
Fused Quartz Tubes & Pipes
Transparent fused silica tubes with outer diameters from 2 mm to 500 mm. Highly specialized options include ozone-free quartz tubes, ultraviolet filtering quartz tubes, and heavy-duty fishing bulb shells designed for demanding operating environments.
Semiconductor Quartzware
Precision-machined diffusion furnace core tubes, quartz boats, wafer carriers, supports, acid-cleaning tanks, transparent quartz crucibles, and customized quartz vacuum flanges manufactured to tight tolerances for wafer fabrication.
Purity Materials & Optics
Supply of 13 categories of ultra-high purity quartz sand with total conventional metallic impurities below 20 ppm, high-transmittance solid quartz rods (Ø1.5–80 mm), and high-grade amorphous quartz particles for optical thin-film coating.
R&D Innovation & International Standards
Technological innovation is our core foundation. Our 320 mm diameter high-purity quartz tube for large-scale integrated circuit processing was formally selected as a Science and Technology Support (Industrial) Project in Jiangsu Province. In addition, our self-developed 520 mm large-diameter high-purity quartz pipe has passed preliminary national reviews for new industrial products.
VEZLO Quartz has systematically applied for provincial special funds dedicated to commercializing key components of wafer oxidation and diffusion furnaces targeting 14-inch-plus wafer lines. Investing over RMB 5 million annually into research and process optimization, we export high-reliability quartzware to international procurement partners throughout Germany, the United Kingdom, the United States, France, Russia, Taiwan, and across more than 20 domestic provinces.
