The Manufacturing Process of Color Coated Aluminum Strip

The color coated aluminum strip is a kind of aluminum strip whose surface has been coated and colored. Because of good flatness, corrosion resistance, decoration, and mechanical properties, it is favored by the market and is widely used in architectural decoration, food packaging, electronic appliances,etc.
Its some popular uses include cosmetic packaging, gutter, shutter, car plate, window spacer, lighting, etc. According to the coating, it is divided into relatively high-end fluorocarbon color coating and low-end polyester color coating. How to color the aluminum strip? There are three aspects we need to place premium on.

Firstly, the choice of materials is very important. Different alloys can be dyed into different colors after anodizing. The aluminum alloys containing copper and silicon will be dyed black or dark. If you don’t need anodizing, the choice will be richer.
Secondly, It is necessary to control the thickness of the oxide film. Different thicknesses and transparency have a certain impact on the dyeing effect of the product. Generally, the thickness of the oxide film is controlled to about 10um, which can achieve the best dyeing effect during the dyeing process.
Thirdly, The concentration of colored aluminum strip dyeing solution should also be controlled. The effect of dyeing with different concentrations is very different. If the concentration is not controlled well, the dyed color will be uneven and the appearance of the pattern will be affected.
Finally, we should have a good control of the temperature of the dyeing solution. Whether it is cold dyeing or hot dyeing, the temperature and dyeing time must be controlled, otherwise, the final dyeing effect will be uneven.
