Aluminum profiles can appear in different colors through electrolytic coloring, so they are favored by all walks of life. Our more common colors are champagne, with bright colors and full tones. If the coloring of aluminum profiles is not handled well, it will cause serious problems. Chromatic aberration. What are the factors that affect the electrolytic coloring of aluminum profiles? The editor will introduce to you below. 1. Extrusion process mold state, temperature and speed will have a certain impact on electrolytic coloring. When aluminum profile is produced, mold design should make the feed material fully integrated, otherwise the surface of aluminum profile is prone to color delamination, so use it during extrusion. The state of the mold and the extrusion lines on the surface of the profile will also affect the oxidation and coloring. 2. Anodizing Anodizing has a very large impact on electrolytic coloring. When using a deep vertical oxidation tank, the temperature is too high and the oxidation bath solution will dissolve the oxide film intensified, resulting in an increase in the pore size of the anodic oxide film surface. On the contrary, the pore size is smaller, which leads to the coloring of the surface of the aluminum profile. The above are the two factors that affect the coloring of aluminum profiles. I hope I can help you. If you have any questions, you can consult the editor.
