Custom Quartz Glass Fabrication & Machining
Custom quartz glass is high-purity fused silica cut, machined and formed into a part built to your exact drawing rather than a catalogue size. From a single prototype to a production run, FGQuartz turns your dimensions, tolerances and application into finished custom fused silica components — tubes, rods, plates, boats, crucibles and complex assemblies. Manufacturing custom quartz components since 2005 in Lianyungang, China, we ship to buyers worldwide with no minimum order on custom parts.

What Is Custom Quartz Glass?
Custom quartz glass means a fused silica part made specifically for your application instead of being chosen from a standard list. You provide a drawing, a sample, or simply your dimensions and what the part must do, and we machine and form high-purity quartz to match — including features that no catalogue item offers.
When do you need custom rather than standard? Whenever dimensions fall outside common sizes, when a part needs special features (flanges, ports, holes, bends, sealed ends, custom profiles), or when the design is unique to your equipment. We build all of these from the same facility, with the right material grade matched to your use case.
Our Custom Quartz Fabrication Capabilities
CNC Machining
Precision cutting, grinding and milling of fused silica to tight dimensions and clean surfaces.
Flame Working
Oxy-hydrogen forming, joining and shaping to build complex assemblies and bends.
Fire Polishing
Smooth, optically clean ends and surfaces for sealing, coupling and clarity.
Cutting & Grinding
Cut to length and size, square ends and ground diameters held to tolerance.
Welding & Joining
Flange welding and tube/plate joining for vacuum and process connections.
Drilling & Ports
Holes, side ports, counterbores and steps for gas inlets and thermocouples.
Bending & Forming
Elbows, coils and shaped sections formed to your geometry.
Polishing & Finishing
Lapping and single- or double-side polishing for optical-grade surfaces.
Custom Quartz Components We Make
Every product in our range can be built to custom dimensions and features. Start from a standard type below and tell us what to change, or send a drawing for a fully bespoke part.
Custom Quartz Tubes
Custom diameters and lengths with flanges, sealed ends, side ports and bends.
Custom Quartz Rods
Cut, polished, ground, drilled or shaped solid rods to your drawing.
Custom Quartz Plates
Cut-to-size windows and substrates, polished, drilled and edge-finished.
Custom Quartz Crucibles
Crucibles to your diameter, height, wall and shape, with optional lid.
Complex Assemblies
Multi-part welded assemblies and specialty shapes that combine several features.
Built entirely to drawing
How to Order a Custom Part
1 · Send your drawing
Share a DXF, STEP or IGES file, a sample, or just dimensions and what the part must do.
2 · Material & review
Our team recommends the right grade and finish for your application and confirms feasibility.
3 · Quote & prototype
You receive a quote and lead time; we can make a single prototype before any volume run.
4 · Production & delivery
On approval we produce and inspect your order and ship internationally.

Industries We Build Custom Quartz Glass For
Solar Photovoltaic
Crucibles, diffusion tubes and boats for PV silicon processing.
Optical & Laser
Windows, substrates and light-guide parts for photonic systems.
High-Temperature Industry
Heater and furnace tubes, protection tubes and viewing windows.
Custom Options & What to Specify
| Shape | Tube, rod, plate, boat, crucible or assembly |
| Dimensions | Diameter, length, thickness and tolerances |
| Appearance | Clear or opaque |
| Surface | As-worked, ground, fire-polished or optically polished |
| Features | Flanges, ports, holes, bends, sealed ends, lids, spouts |
| Volume | Single prototype to production — no MOQ |
| Grade | Matched to your application & confirmed before production |
We carry several material grades; the exact grade and purity level are recommended by our team based on your use case rather than ordered from a code, to avoid mismatches.
Quality Control & Why FGQuartz
Every custom quartz glass part goes through a strict in-house quality process, with inspection at each stage:
- Raw-material purity verification
- Dimensional inspection against your drawing on every order
- Surface, edge and feature quality check
- Optical and thermal performance testing where specified
Backed by experience since 2005, full in-house machining and flame working, a stable high-purity material supply, no minimum order and international shipping, FGQuartz turns drawings into finished custom fused silica parts for semiconductor, solar, optical, fiber, laboratory and industrial customers.
Custom Quartz Glass FAQ
What is custom quartz glass?
It is a fused silica part made to your drawing or specification — custom dimensions, features and finishes — rather than a standard catalogue item.
Do you have a minimum order quantity?
No. There is no MOQ on custom parts. We make single prototypes through to full production runs.
What file formats do you accept?
We accept DXF, STEP and IGES files. You can also send a dimensioned sketch, a sample, or just your sizes and what the part must do.
What can you fabricate?
We machine, cut, grind, polish, fire-polish, drill, bend, weld and form custom tubes, rods, plates, boats, crucibles and complex assemblies.
Can you make a single prototype?
Yes. A one-off prototype is welcome, and we can scale the same design up to production once it is approved.
Which material grade will my part use?
We carry several grades and recommend the right one for your application, confirming the material and purity level with you before production rather than asking you to pick a code.
Can you work from a sample instead of a drawing?
Yes. Send a physical sample or a photo with key dimensions and we can reproduce or adapt the part.
Do you provide engineering support?
Yes. If your design is incomplete, our engineers help finalise dimensions, features and material choice.
Do you ship internationally?
Yes. FGQuartz ships custom quartz glass orders internationally and handles export documentation.
