OEM/ODM Fused Silica Crucible Factory & Exporter for Fort Worth

Our raw materials are sourced from ultra-pure natural quartz veins in Donghai, refined using acid leaching, flotation, and magnetic separation to remove alkali and transition metals. For our highest-grade arc-fused crucibles, total iron (Fe) is guaranteed < 0.2 ppm, aluminum (Al) < 14 ppm, and combined sodium/potassium < 1.5 ppm. Every batch destined for aerospace vacuum induction melting (VIM) is accompanied by an ICP-MS (Inductively Coupled Plasma Mass Spectrometry) inspection certificate, ensuring compliance with ASTM and military-grade casting standards.

For urgent prototypes or standard catalogue dimensions (tubes, standard crucibles, plates), dispatch occurs within 3 to 7 business days via priority international air express (DHL/FedEx/UPS) into DFW International Airport, clearing customs in approximately 5 to 8 business days total door-to-door. For high-volume production orders (e.g., containerized slip-cast crucibles or large diffusion tubes), freight is shipped via sea intermodal routes to the Port of Houston or West Coast ports, followed by direct BNSF/Union Pacific rail into the AllianceTexas Logistics Hub in Fort Worth (typical transit: 22 to 28 calendar days).

Yes. OEM and ODM manufacturing from engineering drawings represents our core operational model. We support 2D drawings (PDF, DWG, DXF) and 3D CAD files (STEP, IGES, SolidWorks). Our in-house manufacturing lines feature CNC 4-axis ultrasonic diamond machining centers and robotic flame lathes, enabling us to mill custom pouring lips, drill blind thermocouple holes with precise bottom wall thickness, and weld quartz support skirts or flanges with high concentricity.

Clear fused quartz can be utilized continuously up to 1100°C–1150°C and for short-duration thermal peaks up to 1450°C. In high-vacuum environments (< 10⁻³ Torr), amorphous silica begins forming a surface cristobalite skin if exposed to temperatures above 1200°C for prolonged intervals, particularly if alkaline dust, fingerprints, or metal vapors are present. To mitigate devitrification in Fort Worth foundries, we recommend maintaining clean vacuum chamber conditions and opting for our high-temperature hydrothermally baked, low-OH fused silica series.

We understand that aerospace research teams and prototype testing lines at facilities like Lockheed Martin, Bell, or university labs cannot commit to container loads without proof of process. We maintain a flexible MOQ policy: standard crucibles and custom prototypes start at just 1 to 5 pieces. Small precision quartz wafers, optical discs, and test tubes generally carry an MOQ of 50 to 100 units. Prototype mold and tooling fees are credited toward subsequent batch production contracts.

We maintain an industry-leading breakage rate of less than 0.1% due to our engineered export packaging system. Every part is cleanroom-washed, bubble-cushioned, and nested inside form-fitting polyurethane or EPE shock foam within heavy-duty double-wall cartons or custom wooden crates. All export shipments carry comprehensive CIF/DDP marine and air cargo insurance. In the rare event that damage occurs during customs inspection or transit, we provide zero-cost emergency manufacturing replacement upon submission of photographic evidence within 48 hours of receipt.
