What Is Stainless Steel Water Bottle
This container jug, carrying water liquid anywhere, is made from stainless steel material.
Stainless steel water bottle is the best alternative for single-use plastic water bottle to reduce plastic pollution globally. The stainless steel 18-8 material is reusable, eco-friendly, compliant with California Prop 65 regulations and Title 21 of the FDA Code of Federal Regulations. It is Non-Toxic, BPA-Free, and is now widely used for kitchenware, tableware, automotive and medical industries.
A single wall stainless steel bottle is lightweight to carry and can be filled with boiling water during the outdoor camping living as well.
The double wall stainless steel water bottle, also named vacuum flask or thermos flask, is now getting more and more popular globally due to the vacuum insulated layer between the double walls, which can prevent heat moving by convection to keep beverage ice cold for 24 hours or hot for 12 hours without condensation issue on its outer shell surface. There is also a copper lining on the inner walls to prevent heat transfer by radiation.
How to Make Double Wall Stainless Steel Water Bottle
The major manufacturing production processes of stainless steel water bottle is:
- Bottle 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.)
- Bottle Cap/Lid Production: 1. plastic raw material → 2. injection molding → 3. assembly
- Bottle 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
Market Overview And Prospect Trend of the Stainless Steel Vacuum Flask Industry in 2021
The stainless steel thermos bottle is made of double walls stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and the air in the interlayer between the inner tank and the outer shell is drawn out by vacuum technology to achieve the preservation of heat.
The global manufacturers of vacuum flasks include Thermos, Hals, Nanlong Group, Xiongtai, Ecoshine, ZOJIRUSHI, etc. The world’s top 20 manufacturers together account for approximately 20% of the market share.
At present, China is the world’s largest production manufacturer of vacuum flask, accounting for approximately 65% of the market.
In 2020, the global stainless steel vacuum flask market has reached 24.7 billion $USD, and is expected to reach 34.2 billion $USD in 2026, with a compound annual growth rate (CAGR) of 4.8%.
