How can we improve the appearance of aluminium sheets during machining? Not all aluminium sheets will have a good appearance after machining, some may even have imperfections such as burrs, scratches and oil stains on the surface. Such aluminium sheets may have certain limitations in use. So, what exactly should we do to improve the quality of the appearance of aluminium sheets when processing? Let's take a look together today!

The first thing we need to pay attention to is the composition and purity of the aluminium sheet. The surface treatment of aluminium products before oxidation material composition as well as the purity of the aluminum oxidation of the influence of the quality of the oxide film layer has long been known to science and technology workers. Secondly, the surface processing quality of aluminium product sheets seriously affects the quality of anodic oxidation products. We need to pay attention to the pre-treatment and milling treatment in production so that we can lay a good foundation for the subsequent surface treatment. For example, and in a good production process, aluminium product sheets are milled, smooth as a mirror, and oxidised to excellent quality. In bad industrial production, for aluminium sheets that have not been milled, they tend to be less glossy, with very serious bubbles, scratches and heavy skin roughness, so that after anodising, these imperfections still show up. As for some of the more decorative processes such as a variety of pattern printing, heat transfer printing, etc. due to the quality of the surface state of the plate is bad and caused by the poor effect of the phenomenon is particularly serious. So improving the quality of the appearance of the plate becomes an important part of ensuring the best quality of aluminium oxidation. And these two are basically the most important highlights to note when dealing with the surface of aluminium sheets. Of course, there are some other measures to ensure the high quality appearance of aluminium sheets, and we welcome you to consult or buy our aluminium sheets.
