High-Performance Fused Silica Plates & Custom Quartz Assemblies
Manufactured from high-purity raw silica (≥99.99% SiO&sub2;) using continuous fusion and electric vacuum melting. Engineered specifically to withstand extreme temperature cycling and harsh chemical aggression.
Mission-Critical Applications of Fused Silica Plates Across Cuba
From pharmaceutical synthesis in Havana to metallurgical nickel refinement in Holguín, fused silica components provide unrivaled thermal, optical, and mechanical endurance in Cuba's primary industrial sectors.
Biopharma & Vaccine Production
Crucial for Cuba's biotechnology institutes (such as BioCubaFarma clusters). Used in deep UV spectrophotometry windows, high-purity reagent digestion cells, and sterilizable cell-culture observation viewports where zero elemental leaching is mandatory.
Nickel & Cobalt Metallurgy Viewports
Heavy-duty fused quartz sight glass plates installed in Moa's high-pressure acid leach (HPAL) autoclaves and calcination kilns. Resistant to corrosive sulfuric gases and continuous working temperatures exceeding 1100°C.
Sugar Refining & Distillation Optics
Employed across Cuban sugar processing mills (AZCUBA) and rum distilleries. Fused silica polarimeter test tubes, refractometer prism plates, and boiler level gauges maintain crystalline clarity without thermal etching.
Solar PV & UV Photolysis Infrastructure
High ultraviolet transmittance plates (JGS1) deployed in solar testing rigs, UV-curing systems, and photocatalytic wastewater treatment plants across national energy diversification projects.
Academic XRD & BET Analysis
Standard zero-background XRD sample holders, BET surface area sorption tubes, and quartz glass crucibles engineered for the University of Havana and Cuban Academy of Sciences materials research labs.
High-Voltage & Marine Sensors
Serving as dielectric barrier plates, high-intensity discharge (HID) lamp covers, and salt-mist-resistant maritime telemetry windows along the Cuban coastal tracking and lighthouse network.

Optical Silica Grade Guide
JGS1 · Synthetic Silica 185 - 2500 nm
Fabricated via SiCl&sub4; vapor phase hydrolysis. Completely bubble-free with superior deep-ultraviolet (DUV) transmission. Optimal for excimer laser systems and photochemical analysis.
JGS2 · Fused Quartz 220 - 2500 nm
Melted from purified natural crystalline silica under high temperature. Industry workhorse for industrial sight glasses, kiln furnace windows, and general optical viewports.
JGS3 · Infrared Grade 260 - 3500 nm
Vacuum-melted low-hydroxyl (OH ≤ 5 ppm) quartz glass. Eliminates the ~2.73 μm absorption band, making it indispensable for infrared heating tubes and pyrometric instrumentation.
Market Evolution & Sourcing Challenges in Cuba
Navigating technical glass imports in Cuba requires addressing trade compliance, customs documentation, maritime logistics safety, and custom dimensional versatility.
1. Shift Toward Direct Factory Sourcing
Cuban state enterprises and private industrial entities (MIPYMEs) are increasingly moving away from high-markup third-party European intermediaries. Sourcing direct from China's quartz capital (Donghai County) cuts procurement costs by 35%–50% while unlocking drawing-specific manufacturing capabilities.
2. High Shock Packaging for Maritime Freight
Glass consignments destined for ports like Mariel or Havana require reinforced multi-stage shock mitigation. Our export process utilizes custom vacuum-sealed foam shells, corner reinforcements, and desiccated wooden crates to counter high-humidity maritime transit.
3. Strict Chemical Purity Verification
With local bio-pharmaceutical labs expanding antibiotic, antibody, and biosimilar facilities, procurement officers require third-party batch spectrographic analysis verifying iron (Fe ≤ 0.2 ppm) and aluminum (Al ≤ 14 ppm) content to eliminate ionic leaching into cultures.
4. Streamlined Drawing & RFQ Turnaround
Local Cuban engineers often need custom-cut viewports for aging vintage equipment (Soviet, European, or modern Chinese lines). Zunex bridges this gap by directly converting CAD/STEP drawings into precision laser-cut quartz glass without costly retooling delays.
Engineering Rigor Backed by Donghai Crystal Capital Roots
Headquartered in Donghai County, Jiangsu, China — the world's most concentrated silicon material industrial base — we merge pristine raw quartz resources with high-precision fabrication.
Laser Micro-Finishing
Advanced quartz laser finishing equipment enables ultra-clean drilling, chamfering, micro-grooving, and step slicing without micro-fissures or edge chipping.
Fast Engineering Response
100% verified response rate with engineering feedback delivered in under 2 hours. Material specialists verify drawings, tolerances, and operational heat cycles immediately.
Safe Global Logistics
Tailored export packaging featuring shock-damped multilayer polyethylene padding and IPPC fumigated crates certified for long-distance maritime and air shipping.
Rigorous Batch Inspection
Every single plate undergoes strict dimensional interferometry, polariscopic stress checks, surface roughness tests (Ra ≤ 0.2 nm), and bubble/inclusion audits.
