  1. Body Production: 1.raw material → 2.shaping of outer cup and inner tank → 3.welding getter on the bottom piece → 4. copper lining on the surface of inner tank (optional) → 5. welding to join the outer shell with inner tank together → 6. ultrasonic cleaning → 7. vacuum producing (test vacuum 100% first time) → 8. electrolysis → 9. polishing (test vacuum 100% second time) → 10. decoration (painting, powder coating, water transfer, heat transfer printing, laser engraving, silk-screen printing etc.)
  2. Cap/Lid Production: 1. plastic raw material → 2. injection molding → 3. assembly
  3. Assembly and Packaging: 1. confirm packaging requirement per PO → 2. prepare all parts → 3. cleaning dust → 4. inspect parts → 5. assembly bottle body and cap → 6. add sticker or label → 7. on-line 100% inspection → 8. pack into gift box → 9. pack into carton box → Finish
