Precision Engineered Insulated Stainleѕѕ Steel Bottle Production Workflow​​

At QIQING, we implement a vertically integrated manufacturing system combining advanced CNC tooling with stringent quality controls. Our 8-stage production protocol ensures premium durability and thermal performance:

​​Digital Prototyping & Design Validation​​

Collaborative R&D teams utilize CAD/CAM software to optimize ergonomic profiles and double-wall vacuum geometries, supported by FEM structural simulations for stress distribution analysis.

​​Precision Tooling Development​​

Certified technicians create hardened steel molds using 5-axis CNC machining centers (as shown in Image 1), achieving ±0.02mm dimensional accuracy. Hydraulic presses rated at 200-400T ensure consistent cup blank formation from 304/316 food-grade stainless coils.

​​Metal Fabrication Excellence​​

Automated TIG welding stations with argon gas shielding create oxidation-free seams. Secondary processes include:

• Necking/Flaring: Computerized spin forming machines
• Surface Preparation: Electropolishing & ultrasonic degreasing

​​Vacuum Insulation Engineering​​

Triple-stage vacuum chambers achieve 10-5 Torr vacuum levels, paired with copper flash coating for optimized thermal reflection. 100% pressure decay testing ensures permanent vacuum integrity.

​​Multi-Layer Quality Assurance​​

Dimensional checks: Laser scanners & CMM

Leak testing: 0.15MPa hydrostatic pressure

Insulation validation: 24hr thermal retention trials

​​Aesthetic Finishing​​

Automated powder coating lines apply FDA-compliant colors (RAL/Pantone matched), followed by 200°C curing. Alternative finishes:

Brushed/Satin: CNC abrasive belt systems

PVD Coating: Wear-resistant metallic layers

​​Branding Solutions​​

Laser engraving (0.1mm resolution) or pad printing (6-color process) applies logos/text with MIL-STD durability ratings. Custom packaging imprinting available.

​​Smart Packaging​​

Cleanroom assembly areas employ:

Automated foam inserter machines

Anti-fog film wrapping

Barcode-tracked carton packaging
