How to Color Embossed Aluminum Sheet Metal

The embossed aluminum sheet metal is highly favored because of its decoration,high corrosion resistance, good sliding resistance, and light weight. It can be seen everywhere in large factories, office building, shopping mall entrances and electrical enclosure manufacturing.

During the manufacturing of embossed aluminum sheet, the stucco embossed aluminium sheet factory may encounter the problem of unsatisfactory dyeing, resulting in poor dyeing effect. Then how to deal with this problem? This is our solution.

1. Choose right aluminum plate

In the production process, the pure aluminum sheet, Al-Mg aluminum sheet and Al-Mn aluminum plate has better coloring effect after anodizing. For aluminum plates with high content of silicon or copper, only dark and black can be dyed during the dyeing process.

2. Keep a good control of the thickness of the oxide film

he oxide film refers to the thickness, porosity, transparency, etc. of the aluminum film layer. The thickness of the film layer in the aluminum plate should be kept above 10um, then we can get a good dyeing effect.

3. Pay attention to the concentration of dyeing solution

There is a certain relationship between the concentration of the dyeing solution and the dyeing effect. If the aluminum plate is light-colored, the concentration can be lower, otherwise, it can be higher.

In order to enhance the absorption of dyeing, low concentration colors will be used for further dyeing, so that the dye molecules can penetrate into the depth of the pores of the oxide film more uniformly, which can make the dyed colors more harmonious and firm.

4. Keep an eye on the temperature of the dyeing solution

Aluminum dyeing is divided into cold dyeing and hot dyeing. Cold dyeing takes a long time to get the ideal effect and the uniformity of the dyed colors is relatively easy to master. The hot dyeing is of a relatively short time and it is difficult to control the color.

The temperature of thermal dyeing is usually in the range of 40-60 ° C. If the temperature is too high, it will reduce the adsorption of dyeing. As an embossed aluminium sheet manufacturer, Haomei Aluminum can offer you rich kinds of embossed aluminum sheet metal.
