Production Processes

Production processes for aluminum foil rolls
Chromating Line
1. Unwinding
2. Degrease (brush)
3. Degrease (dipping bath)
4. Neutralization
5. Chromating
6. Drying
7. Rewinding
The chromating line, a kind of surface treatment line, functions to clean the lubricating grease, anti-oxidization grease, silicon, magnesium, copper and many other impurities on the surface of aluminum foil.
During chromating for our aluminium foils, we acquire high quality chemical raw materials and technologies from Germany Henkel Group to guarantee surface treatment quality. After surface treatment, the aluminium foil surface will be covered with a layer of high intensity honeycomb-style oxide film. This oxide film functions as an agent to make paint and aluminum foil adhesive with each other.

Precision coating line
1. Unwinding
2. Drying
3. 3-roller coating
4. Baking finish
5. Transfer
6. Storage
7. QC
8. Rewinding
The precision line functions to coat paints on chromated aluminum foil rolls. We adopt high precision three-roll reverse coating machines to conduct surface coating in enclosed and dust free environment. Thus, the coating thickness and coating quality can both be guaranteed.
The oven is divided into four temperature-controllable sections. This ensures the optimum condition of surface coating\'s solvent resistance, hardness, and flexibility, etc. Hence, our surface coated aluminum foil coils are characterized by high glossiness, strong adhesive force and corrosion resistance.
