What Is Stainless Steel Vacuum Flask
A container jug which can carry on water liquid anywhere to go, and make with stainless steel material, it is stainless steel water bottle.
Stainless steel water bottle are best alternative for single one used plastic water bottle to save 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, Non-Toxic, BPA-Free, now is widely use for kitchenware, tableware, automotive and medical industrial.
A single wall stainless steel bottle is lightweight to carry your water liquid on the go, also can be boiling water during the outdoor camping living as well.
The double wall stainless steel water bottle also named vacuum flask or thermos flask now is getting more and more popular globally due to there’s a vacuum insulated layer between the double walls to prevent heat moving by convection to keep water liquid beverage ice cold 24 hours up and water hot 12 hours up without condensation issue from its outer shell surface, plus 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 vacuum flask 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
It’s more than 100 production processes for stainless steel Bottle, usually takes 30 days more production lead time for an order from raw material to final shipment ready, more details you wan to know can watch below video or check here to read more: https://www.ecowayhouseware.com/manufacturing-processes/Play Video
