20 Years of Excellence
in Quartz Glass

Our Story

Founded in 2005 in Lianyungang, Jiangsu Province, FGQuartz has established itself as a leading manufacturer of ultra-pure quartz glass products in China and globally. With over two decades of expertise, we specialize in producing high-precision quartz components that meet the stringent requirements of semiconductor fabrication, optical fiber manufacturing, and advanced scientific research.

Our journey began with a vision to provide the Chinese semiconductor and optical industries with domestically-produced, world-class quartz glass materials. Through continuous investment in technology, talent, and quality systems, we have grown from a small workshop to a 15,000 square meter state-of-the-art manufacturing facility serving over 500 clients across 30+ countries.

Located in Lianyungang, a strategic port city in Jiangsu Province, we benefit from excellent logistics infrastructure and proximity to premium raw material sources. Our facility is equipped with advanced fusion furnaces, precision CNC machining centers, and automated polishing systems that enable us to manufacture components with tight tolerances (±0.1mm) and superior surface finishes (Ra < 0.4μm).

Today, FGQuartz stands as a trusted partner for leading companies in semiconductor, telecommunications, solar energy, and research sectors. Our commitment to 99.99% purity standards, precision engineering, and customer service has earned us recognition as a reliable supplier of critical quartz glass components for the world’s most demanding applications.

Two decades of expertise, cutting-edge manufacturing capabilities, and unwavering commitment to quality make us the preferred partner for high-purity quartz glass solutions.

ISO 9001:2015 certified manufacturing processes ensure every product meets or exceeds international quality standards. Our comprehensive quality control system includes raw material inspection, in-process monitoring, and final product testing using advanced analytical equipment.

We utilize ICP-MS analysis for impurity verification, optical spectrometry for transmission testing, and precision metrology for dimensional accuracy. Every batch includes detailed certificates of analysis documenting purity levels, dimensions, and performance characteristics.

Our 15,000m² state-of-the-art facility features advanced fusion furnaces, precision CNC machining centers, and automated polishing systems. We utilize both flame fusion and electric fusion techniques to produce quartz glass with optimal properties for specific applications.
