Why Choose FGQuartz
Two decades of specialist quartz manufacturing, end-to-end in-house control, and engineering support that starts with your application.
20 Years’ Experience
A specialist quartz glass maker since 2005, with the process know-how that turns raw silica into reliable, repeatable components.
Strict In-House Quality Process
Every stage — from incoming material to final inspection — is controlled in-house, and each order ships with full traceability.
Custom & OEM, No MOQ
From a single prototype to volume production, we build to your drawing — flame working, CNC machining, welding and finishing.
Right Grade for the Job
We match the material grade to your application rather than forcing one spec, so you pay for the performance you actually need.
Engineering Support
Our team advises on material, geometry and finish up front — and replies to inquiries within 24 hours.
Worldwide Shipping
From our port city of Lianyungang, we deliver to 500+ clients across 40+ countries with secure, tracked logistics.
Manufacturing in Our Own Fused Silica Works
From a 15,000 m² facility in Lianyungang, China, we run the full process in-house — fusion, forming, CNC machining, flame working, fire polishing, annealing, precision cleaning and inspection. Controlling every stage is how we hold purity, geometry and batch-to-batch consistency.View Technical Specifications
