Quick Answer: FGQuartz is an ISO 9001-certified quartz glass manufacturer, founded in 2005 in Lianyungang, China, supplying seven core fused silica product lines — tubes, rods, plates, wafer boats, crucibles, tanks, and inline heaters — plus fully custom fabrication for semiconductor, solar PV, optical, fiber-optic, and laboratory customers in 40+ countries. No minimum order quantity, quotes typically within 24 business hours.
Seven catalog families, plus fully custom.
Standard geometries from stock. Non-standard parts to CAD. One facility covers hot work and CNC.
Process, diffusion, and large-diameter tubes. Flanges, bends, side ports, and weldments to drawing.
Solid fused silica rods, 3–300 mm diameter, precision-ground or optically polished.
Process-grade plates and JGS1/JGS2/JGS3 optical windows, drilled, milled, and DSP-polished.
Horizontal and vertical boats for 2–12″ wafers and M10/G12 solar formats. Slot pitch to ±0.05 mm.
CZ and DS crucibles for crystal growth, calcination, and high-purity chemical containment.
Seamless wet-bench tanks with overflow weirs, drains, and custom geometry for aggressive chemistries.
Flow-through heating chambers for ultra-pure or corrosive fluids, with zero metal contact on the wetted path.
Custom Fabrication
If a catalog part won’t fit the process, we build the one that will.
DXF, STEP, IGES, and PDF drawings accepted. Reverse engineering from worn samples is available. DFM review is included with the quotation.
Thermal forming and diamond CNC under one roof.
Fused silica is hard, brittle, and only workable at extreme temperature. Geometry decides the route: CNC for tolerances, flame for joints and bends, fire polish for surface continuity. We set that route at the drawing stage.

Dimensional modification, precision cuts
Bending, blowing, oxy-hydrogen work
Vacuum sealing, fire polishing
Multi-axis grooving, drilling, threading
Multi-port assembly integration
OEM manufacturing to print
Built for front-end fabs, crystal growth, optics, and the laboratory.
Process tubes, wafer boats, injectors, liners, and wet-bench vessels for diffusion, oxidation, LPCVD, and anneal.
CZ and DS crucibles, diffusion tubes, and wafer carriers for PERC, TOPCon, and HJT lines.
JGS-grade windows, rods, and custom optics from deep UV through IR.
High-purity tubes, rods, and assemblies for preform and draw environments.
Beakers, flasks, crucibles, combustion tubes, and custom apparatus to 1200°C.
Furnace tubes, tanks, and structural parts where thermal shock resistance is non-negotiable.
