What is stainless steel vacuum flask
Stainless steel vacuum flask is a water bottle made by stainless steel material to carry water liquid to go anywhere for your daily hydration drinking, with vacuum insulation technique plus copper lining shield to keep water liquid hot 12 hours up and ice cold 24 hours up.
How does stainless steel bottle work
A double wall vacuum insulated stainless steel vacuum flask:
How does it work?
With traditional water bottle, heat or cold finds its way inside through the process of convection;
Vacuum insulated stainless steel vacuum flask with a vacuum layer which is airless space between the double walls, virtually eliminating the convection process and temperature change.
Your drink will stay ice cold or steamy hot without condensation issue when touching it no matter what the forecast.

- Purchase raw material
- Cutting stainless steel tube
- Shape forming with water swelling ( or deep drawing forming) depends on the design requirement
- Cutting into 2 pieces
- Mouth forming with threads if need
- Matching and welding the mouth of stainless steel vacuum flask (the out wall and inner wall join together then do Laser welding)
- Welding the bottom cap and with an attachment of Getter
- Vacuum process inside the vacuum machinery around 4 hours to create vacuum insulated layer between the double walls stainless steel
- Vacuum Insulation Test (measure the stainless steel bottle tumbler is good quality or faulty on vacuum insulation) 100%
- Electrolysis for the inside of the stainless steel vacuum insulated flask (it can clean the dirty to have nice surface, also create a layer on the inner surface to have good corrosion prevention)
- Inspection of electrolysis quality 100%
- Polishing the surface of outer wall of the stainless steel insulated flask
- Inspection of Polishing quality 100%
- Vacuum insulation test 100% second time
- Decoration (spray painting, powder coating, water transfer painting, heat transfer printing, logo printing or laser engraving etc.)
- Assembly with caps, cleaning, inspection, packaging
- Out going final QC inspection
When you need to create a custom design stainless steel vacuum flask, you should need to know How Much does it cost for manufacturing? and what can affect the cost?
In this situation, you are in right place here that we Ecoway Houseware Limited can help you to find out the important thing you should know about Stainless Steel Water Bottle Manufacturing prices costs.
The stainless steel water bottle cost can be vary different depending on what is your custom parts design and the order quantities.
There are some basic information of stainless steel bottle pricing you need to know. For example, product design cost it will begin when you set up the project even it’s not start production; the material not only affect the quality also it is the main cost of your custom bottle products; the order quantities could affect a lot of the whole cost, and affect the shipment cost for your water bottle products;
You also need to think about:
- The timing of your order
- The cost of using surface treatment
- Labor costs
