Onsite Verified Manufacturer & Exporter
VEZLO Quartz Products Co., Ltd. is situated in the globally recognized "China Quartz Center" — Donghai County, Jiangsu Province. With direct geographic access to premium silicon deposits and a mature regional industrial chain, our company spans an area of 50 mu with fixed assets surpassing RMB 10 million. We specialize in producing premium quartz glass products and high-purity piping systems engineered for electric light sources, sterilization fixtures, chemical pipelines, optical communication, high-temperature thermal equipment, and semiconductor fabrication.
Our core product scope encompasses transparent fused silica glass tubes with an outer diameter range of 2 mm to 500 mm; specialized semiconductor furnace core tubes, quartz boats, wafer carriers, chemical cleaning tanks, high-purity crucibles, and precision ground flanges. We manufacture ozone-free quartz tubes, ultraviolet-filtering tubes, heavy-duty fishing lamp bulb envelopes, 13 proprietary grades of ultra-high purity quartz sand with total metallic impurities below 20 ppm, quartz rods (diameter 1.5–80 mm), and amorphous quartz coating particles for vacuum thin-film optical deposition.
Emphasizing technical excellence and strict quality governance, our products are distributed across more than 20 domestic provinces and municipalities, and exported worldwide to Germany, the United Kingdom, the United States, France, Russia, Taiwan region, and beyond. Every custom order is supported by strict dimensional verification, reliable export packing, and swift engineering feedback within 2 hours.
Sustained capital commitment of no less than RMB 5 million every year fuels our continuous breakthrough in semiconductor-grade quartzware.
Our Ø320mm high-purity quartz tube developed for large-scale integrated circuit (IC) manufacturing was officially endorsed and executed under the Jiangsu Provincial Science and Technology Support (Industrial) Project, meeting stringent thermal and purity parameters.
The newly engineered Ø520mm extra-large diameter high-purity quartz pipe has successfully completed and passed the preliminary national review for new industrial products, significantly expanding domestic manufacturing limits in large-diameter furnace tubes.
VEZLO has qualified for the Jiangsu Provincial Special Fund for Transformation of Scientific and Technological Achievements, focusing on the industrialization of large-diameter quartz glass tubes as crucial components in oxidation and diffusion furnaces for wafer sizes exceeding 14 inches.
