Water bottle manufacturing involves a complex process that requires specialized equipment and materials, which are not normally feasible for individuals to handle at home. However, Everich is a leading water bottle manufacturer in China with over 20 years of experience.
Our fully-owned water bottle factory, “Kingvac,” is capable of manufacturing different types of water bottles, including insulated and BPA-free sports water bottles. Here’s a simple explanation of the steps involved in producing stainless steel water bottles:
Materials and Equipment:
1. Stainless Steel Raw Material:
The inner and outer layers of the bottle are typically made of 304/316 stainless steel for durability and insulation.
2. Welding and Sealing Equipment:
Specialized machines and techniques are used to join the inner and outer layers of the bottle and create an airtight seal.
3. Cap and Gasket:
The cap of the bottle often contains a rubber or silicone gasket to provide a tight seal.
The Manufacturing Process:
1. Fabrication of Bottle Components:
The inner and outer layers of the bottle are manufactured, typically through processes like stainless steel rolling and shaping. The insulating material is prepared according to the design.
2. Assembling the Bottle:
The inner and outer layers are brought together, leaving a gap for the insulating material. The cap is also attached at this stage.
The insulating material is placed between the inner and outer layers. If vacuum insulation is used, air is removed from the space between the layers to create a vacuum, reducing heat transfer.
4. Welding and Sealing:
The bottle is sealed, ensuring that there are no air leaks between the layers. Welding is used to make the bottle airtight.
5. Quality Control:
The finished bottle is thoroughly inspected for any defects or issues that might affect its insulating properties.
The bottle may undergo testing to ensure it meets the specified insulation standards, including tests for heat retention and cold retention.
If you want to create custom water bottles on a smaller scale or as a DIY project, consider using blank stainless steel tumblers and applying your designs or labels using appropriate printing techniques and materials.
