Stainless Steel Bottles

Many people are curious and want to know how vacuum insulated water bottles are made. Here we will show you the manufacturing process of vacuum insulated stainless steel water bottles step by step in detail to help you understand.

Principle of Thermal Insulation

The vacuum insulated stainless steel bottle is generally a container made of stainless steel and a vacuum structure. The vacuum insulation structure can delay the heat dissipation of the liquid such as water inside to achieve the purpose of heat preservation. Most of the inner walls are made of stainless steel with silver or copper plated. The shiny wall can reflect the radiation of hot water. The vacuum structure can block the heat transfer, thus preventing heat convection and achieve the effect of insulation. This is why insulated water bottles can keep the beverage hot or cold for a long time.

Raw Material of Insulated Water Bottles

The material used to make insulated water bottles is stainless steel, which forms the inner bottle and the outer bottle. SUS304 (18 / 8 food grade stainless steel) is the most widely used as stainless steel, and is used in food equipment, general chemical equipment, atomic energy industry, etc. SUS304 is corrosion resistance, heat resistance, low temperature strength and good mechanical properties. SUS304 using temperature: -196 to 800 °C.

Vacuum Insulated Stainless Steel Bottle Tumbler Manufacturing Process

Brief description: Stainless steel arrives at the factory in the form of pines and sheets –> Produce outer bottle and inner bottle –> Assembly and welding –> Vacuuming –> Decorating.
