FOCUSING ON CUSTOMIZED ALUMINUM EXTRUSION PROFILES
Technology
We use 100% original AA-grade 6063 Plus aluminum ingots, which can achieve a shiny surface even after polishing, without any mechanical lines or sand inclusions. We employ top-level wet phosphoric acid coloration for the anodizing process, achieving a film thickness of 12-15μ and enabling automatic repair of scratches. The anodizing treatment is carried out using German KRAUTZBERGER sandblasting machines, ensuring no mechanical damage and guaranteeing the quality of the appearance. Our anodizing tank model SACTT446 ensures that the surface color never fades, and the extrusion precision is maintained within a tolerance of +0 using the Yw 660UST extrusion machine.

“Outstanding Work”
In order to save costs, I asked the supplier to pack only one layer of plastic film, and the plastic film was damaged during transportation, but the aluminum profile was not scratched because the quality is very good. It is glad not to have to spend another sum of money to repurchase. I suggest that other buyers should follow the supplier’s advice to choose the better packaging protection materials when purchasing products.
