Hydrographics Tank

The hydrographics tank, also known as water transfer printing or hydro dipping, is an essential tool for applying three-dimensional printed graphics onto complex surfaces. Here is a detailed description of its components and operation:

Main Components

Tank Structure:

Material: Typically made of stainless steel to resist corrosion and facilitate cleaning.
Size: Varies depending on needs, but must be large enough to fully immerse the object to be decorated.

Heating System:

Function: Maintains the water at the optimal temperature (generally between 25°C and 30°C) to ensure proper activation of the hydrographic film.
Components: May include electric heaters and a thermostat for precise temperature control.

Water Filtration and Circulation System:

Function: Removes film and activator residues from the water to keep it clean and ready for subsequent use.
Components: Circulation pump and filters.

Supports and Grids:

Function: Can be used to hold the film in position on the water surface and facilitate the immersion of the object.
Components: Adjustable nets or grids.

Activator and Sprayers:

Function: The chemical activator is sprayed onto the film to dissolve the water-soluble carrier, leaving only the floating ink on the surface.
Components: Manual or automatic sprayers for even distribution of the activator.

Operation of the Tank

Water Preparation: Fill the tank with water and heat it to the desired temperature.
Film Placement: Cut the hydrographic film to the required size and carefully place it on the water surface, where it will float and soften.
Activator Application: Once the film is properly spread on the water, spray the activator. This step is crucial to dissolve the film’s carrier and activate the ink.
Object Immersion: Slowly immerse the object into the tank through the activated film. The graphic wraps around the object, adhering perfectly to its surface.
Removal and Rinsing: After immersion, remove the object from the tank and rinse to eliminate any remaining activator and unused film.
Drying and Finishing: Dry the object and optionally apply a clear coat to protect the decoration and enhance durability.

Considerations

Safety: It is important to follow safety regulations, especially when handling chemical activators.
Maintenance: The tank requires regular cleaning to keep the water clean and the components in good condition.
Quality of Film and Activator: Using high-quality materials ensures better results and longer-lasting decorations.
