We deploy high-precision CO₂ laser drilling, automated micro-slotting, and CNC grinding to manufacture complex features without generating the micro-cracks common in traditional diamond drilling.
Continuous annealing profiles yield quartz glassware resilient to extreme thermal shock (1100°C directly plunged into water without fracture) and resistant to virtually all acids except HF.
Custom-cut multi-layer EVA foam inserts, vacuum poly packaging, and reinforced wooden crates guarantee shock-free, zero-breakage air/sea freight directly into the Lyon-Saint Exupéry logistics hub.
The greater Lyon area (Auvergne-Rhône-Alpes) serves as France's primary center for chemical engineering, biopharmaceuticals, environmental science, and advanced metallurgy. Our products address specific technical requirements throughout these local industry sectors.
From Saint-Fons to Feyzin, chemical manufacturing and catalyst formulation laboratories rely on our heavy-wall quartz reaction columns, distillation vessels, and custom manifolds for aggressive acid synthesis and high-temperature catalytic reforming where borosilicate fails.
Research hubs in Lyon-Gerland require synthetic silica (JGS1) spectroscopy cells, UV flow channels, and quartz microfluidic plates for deep-UV (254 nm and 185 nm) nucleic acid purification, excimer laser sterilization, and diagnostic analytical columns.
Supplying nearby semiconductor fabrication equipment with high-purity quartz wafer boats, vertical furnace process tubes, thermocouple wells, and bell jars optimized to prevent metallic ionic contamination across wafer thermal processing runs.
Partnering with regional solar initiatives and academic laboratories (such as INSA Lyon and CNRS research institutes) by delivering high-throughput diffusion tubes, ozone-free UV quartz envelopes, and carrier cassettes customized for next-gen tandem cell research.
Supporting Lyon's heritage in technical textiles and advanced polymer polymers with quartz twin-tube infrared emitters, quartz glass heating jackets, and pyrolytic reaction vessels operating consistently up to 1100°C without devitrification.

Strategic structural shifts across regional French high-tech production are reshaping the requirements for imported custom quartz glass.
Lyon engineering houses increasingly shift from standard off-the-shelf catalog items to custom-engineered, step-file-machined quartz reactors. Direct factory DFM reviews bridge rapid prototyping into full pilot-scale series production without recurring tooling overheads.
In response to supply bottlenecks from European tier-1 glass distributors, French industrial purchasers establish direct OEM relationships with verified source factories in Donghai to achieve competitive pricing while securing batch consistency via third-party chemical purity analyses.
With industrial decarbonization programs expanding across the Rhône valley, high-efficiency twin-tube quartz infrared heating modules are replacing conventional gas-fired baking tunnels in plastics, paint drying, and battery electrode processing plants.
Essential guidance on custom tolerances, logistics to France, material compliance, and payment terms for B2B accounts.
All quartz products shipped to the Auvergne-Rhône-Alpes region are protected with custom-molded high-density EVA foam and packed inside multi-layered plywood cases compliant with ISPM 15 standards. We manage DDP or DAP delivery via Lyon-Saint Exupéry Airport (LYS) or consolidated marine freight via Fos-sur-Mer / Marseille with comprehensive transit insurance.
Yes. Our engineering department operates automated CAD/CAM interfaces that translate your STEP, DWG, DXF, or PDF engineering drawings directly into precision CNC grinding and laser-machining programs. We conduct a Design-for-Manufacturability (DFM) verification within two hours to confirm tolerances and thermal stress management.
For precision optical plates and discs, we regularly achieve thickness tolerances of ±0.05 mm, parallelism under 30 arcseconds, and surface roughness of Ra < 0.5 nm (80/50 or 60/40 scratch-dig). Cylindrical tubing is supplied according to DIN ISO 2768-m standards or tailored customer tolerances for vacuum flange compatibility.
Yes. Fused quartz supplied by Zunex Quartz is manufactured from high-purity silicon dioxide (purity ≥ 99.99%) completely free of heavy metals, plasticizers, and SVHC candidates under EU REACH regulation. Chemical analysis reports (GDMS or ICP-MS) certifying elemental impurities are provided with export documentation.
While borosilicate 3.3 softens at approximately 820°C and has a continuous service ceiling of 450°C–500°C, fused quartz operates continuously at 1100°C with a softening point of 1683°C. Quartz exhibits near-zero thermal expansion (5.5 × 10⁻⁷/°C), offering superior thermal shock endurance and higher UV transmission compared to borosilicate.
We actively support university research laboratories, prototyping teams, and small pilot lines. There is no strict MOQ for custom parts: we accept single-piece custom orders (1 pc) for prototype evaluation, with scalable quantity discounts applied as your manufacturing batches increase.
Send your drawings, dimensional requirements, or material specifications. Our engineers will review manufacturability, verify tolerances, and deliver a transparent quotation within 2 hours.
