How stainless steel water bottle is made?

Stainless steel water bottle manufacturing process

  • Manufacture double wall stainless steel insulated water bottle: “Outer wall & inner wall”, manufacture the shape and size as design drawing specs.Stainless steel water bottle manufacturing process
  • Copper Coating: copper coating on the inner wall which enhancing heat preservation performanceStainless steel water bottle manufacturing process
  • Welding: welding the mouth edge, bottom
  • Grinding: grinding the welding seamStainless steel water bottle manufacturing process
  • Vacuum Process: create vacuum space between double wall, and test 100% vacuum insulation
  • Electrolysis: electrolysis process to create a inert layer on the surface of inner wall to make it good surface and not easy  to get rust.
  • Polishing:polishing the bottle flask to have good quality surface.
  • Vacuum Test: test vacuum insulation of stainless steel tumbler 100% againtemperature test
  • Surface treatment: different options for surface treatment, such as spray painting, powder coating, water transfer etc.stainless steel water bottle manufacturing process
  • Custom printing: custom printing with different method, such as pad printing, heat transfer printing, laser etching etc.
  • Inspection and assembly: inspection, asembly with lids, gasket, sleeve, gift box

Quality Control:

The most important of stainless steel vacuum insulated tumbler is vacuum insulation, that’s why we have double “vacuum insulation test” during the whole manufacturing process.

The raw material cost is very important for high end quality stainless steel bottles, we recommend 18-8 Food grade stainless steel.

The polishing quality is very important if no any other surface treatment, our company set full inspection after polising process.

Different surface treatment has different features, we can choose the best way to meet the bottle design and market needs.

Final inspection of your stainless steel vacuum insulated bottle flask is during/after the assembly/packing line.

The Features:

How are insulated water bottles madeThe stainless steel vacuum tumbler keeps hot liquid 12 Hours longer and cold liquid 24 Hours, it based on the manufacturing process and quality control, also affect by the bottle designs.
