  3. Electrolytic Process: Place the water bottle as the anode (connected to the positive terminal) into the anodizing tank, while also placing a cathode (connected to the negative terminal) into the tank. When electricity is applied, the electrolyte in the anodizing tank undergoes an oxidation reaction, forming a uniform oxide layer covering the surface of the water bottle.

  4. Coloring and Decoration: Depending on the desired outcome, the color and appearance of the oxide layer can be altered by controlling the electrolyte and electrolytic conditions. Various dyeing agents or coloring techniques can be employed to achieve different colors and decorative effects in the oxide layer.

  5. Sealing and Post-Treatment: After the anodizing process is completed, the water bottle can undergo sealing treatment to enhance the wear resistance and corrosion resistance of the oxide layer. Additionally, post-treatment steps such as cleaning, polishing, and coating can be performed to improve the surface smoothness and protective properties of the water bottle.

Water bottle thermal transfer

Water bottle thermal transfer, also known as water bottle printing or water bottle decal, is a process of transferring designs, patterns, or graphics onto the surface of a water bottle using heat and pressure. This method allows for customization and personalization of water bottles with various colors, images, and text.

  1. Design Preparation: The desired design or artwork is created using graphic design software or obtained from a digital image. The design should be suitable for thermal transfer printing and sized appropriately to fit the water bottle’s surface.
