Enterprise Overview & Production Foundation
VEZLO Quartz Products Co., Ltd. is located in the heart of Donghai County, Jiangsu Province — universally recognized as "China's Quartz Center" due to its rich, high-purity natural silica mineral reserves and integrated industrial cluster.
Covering an expansive production footprint of 50 mu (approx. 33,000 square meters) with fixed capital assets exceeding RMB 10 million, our plant integrates advanced continuous thermal melting furnaces, precision drawing towers, optical cold-machining lathes, and clean flame-working cleanrooms.
We supply top-tier quartz glass solutions to critical global sectors including semiconductor wafer processing, ultraviolet germicidal sterilization, electric light sources, chemical pipeline engineering, optical communication, and industrial high-temperature heating.
Verified Enterprise Specifications
Audited and verified operational data confirming our manufacturing scale, commercial reliability, and compliance for overseas buyers.
Provincial & National R&D Recognition
Backed by sustained technological development, VEZLO Quartz invests no less than RMB 5 million every year into innovative high-purity quartz projects.
Provincial Science & Technology Support Project
Our self-developed Ø320mm high-purity quartz tube engineered for large-scale integrated circuits (VLSI) was officially approved and accomplished as a prestigious Science and Technology Support (Industrial) Project of Jiangsu Province.
National New Product Preliminary Review
Our breakthrough Ø520mm ultra-large-diameter high-purity quartz pipe successfully passed the preliminary evaluation for National New Products, demonstrating our capacity in super-sized quartz thermal process tubes.
14-Inch+ Wafer Oxidation/Diffusion Project
VEZLO Quartz has systematically applied for the Jiangsu Special Fund for Transformation of Scientific and Technological Achievements, focusing on industrializing large-diameter quartz glass furnace tubes for 14-inch-plus semiconductor fabrication.
Precision Quartz Glass Capabilities
Fabricated with extreme thermal tolerance (softening point ≈1683°C, continuous service at 1100°C) and stringent dimensional controls.
Fused Quartz Glass Tubes (OD 2 - 500mm)
Transparent fused silica glass tubes in arbitrary diameters and lengths. Includes ozone-free quartz tubes (blocking 185nm UV, transmitting 254nm), UV-filtering tubes, and high-intensity fishing bulb envelopes.
13 Grades of Ultra-High Purity Quartz Sand
Refined high-purity natural silica sand with total conventional metallic impurities strictly limited to ≤20ppm, guaranteeing minimal bubble formation and exceptional clarity for optical and semiconductor smelting.
Semiconductor Quartzware & Components
Specialized fabrication of diffusion furnace core tubes, quartz wafer boats, carriers, structural supports, multi-bath cleaning tanks, transparent quartz crucibles, and vacuum-tight quartz flanges.
Quartz Glass Plates, Rods & Optical Materials
Precision-drawn solid quartz rods from Ø1.5mm to 80mm, optical-grade double-side polished sheets and windows, plus amorphous quartz coating particles designed for thin-film optical vacuum deposition.
Trusted by Buyers Across 30+ Countries
In addition to supplying top domestic semiconductor, photovoltaic, and optical equipment manufacturers across more than 20 provinces, VEZLO Quartz has developed mature direct-export supply lines to premier industrial markets worldwide.
Every batch undergoes spectrophotometer UV-Vis transmission analysis, micrometer runout inspection, and polarized thermal stress testing before packaging.
Protected with customized pearl cotton, multi-layer shock absorbent bubble wrap, vacuum sealing, and heavy-duty fumigation-free wooden cases suitable for intercontinental air and sea transit.
Our dedicated bilingual technical engineering team reviews drawings, tolerancing requirements, and thermal specs with an average response time of under 2 hours.
