The influence of extrusion process on oxidation coloring is mainly the influence of die design, extrusion temperature, extrusion speed and cooling method on the surface state and microstructure uniformity of the extruded profile.

1.

The influence of extrusion process on oxidation coloring is mainly the influence of die design, extrusion temperature, extrusion speed, cooling method, etc. on the surface state and tissue uniformity of the extruded profile.

mold design should be able to make the feed fully kneaded, otherwise prone to bright (dark) with defects, the same profile may appear color separation; at the same time, the mold state and profile surface extrusion lines also affect the oxidation coloring. Extrusion temperature, speed, cooling method and cooling time are different, so that the profile organization is not uniform, will also produce color difference.

2. Surface Treatment-Anodizing

Anodizing has a very important influence on the color difference of electrolytic coloring, especially in the production process of vertical oxidation line, two colors are easy to appear, the depth of vertical oxidation tank is 7.5m, and the temperature difference between the upper and lower tank liquids is easy to occur.

3. Conductivity

In the process of anodic oxidation, the conductivity has an effect on the oxide film and will also cause color difference in coloring materials. This problem is mainly easy to occur in horizontal production lines.

is mainly due to the poor conductivity of individual materials during the upper row of oxidized blanks before oxidation, thus making the oxide films relatively different, after coloring, it will produce color difference.

4. Electrolytic Coloring Process Affects

Electrolytic Coloring Process can directly reflect the color difference problem. The current distribution capability of electrolytic coloring liquid has a decisive influence on the uniform coloring of coloring materials. Once the current distribution is uneven, obvious color difference will be caused. The current distribution capability of

bath liquid is mainly related to the conductivity and polarization of the bath liquid. The coloring liquid contains a certain amount of conductive salt, mainly to improve the conductivity of the coloring liquid. When the conductive salt is not added in time, the conductive ability decreases and the current distribution ability decreases, which will cause color difference.
