1, pre-treatment, first using the method of surface cleaning three pattern aluminum price, physical and chemical methods are the most important is the aluminum coil is exposed substrate. Thus, it helps complete the oxidation of the oxide formed the film will be dense. pretreatment can also use some mechanical handling equipment. 2. anodized aluminum after processing through the coil, the matrix anodic oxidation occurs, then that will generate a dense oxide film. 3. closure hole, after the anodic oxidation, the oxide film will be a lot of membrane pores, sealing the membrane pore blocking is to make these three pattern aluminum stock manufacturers, to prevent contamination of the oxide film. This oxide film is transparent, and having adsorptive so some of the metal will be deposited in the three hole pattern aluminum, so that we can reveal the appearance of some original silver-white, many colors, or outside. aluminum means the processing of aluminum and aluminum alloy plate type material. aluminum alloy can be divided into cold-rolled and hot-rolled, the main difference is the difference between the anodic oxidation of hot-rolled aluminum anodizing can do. Different aluminum cold rolling and hot-rolled aluminum manufacturer uses three pattern aluminum, cold rolled aluminum used for mold class, suitable for hot-rolled aluminum stamping stretch on. The same material due to different production process, its physical properties vary greatly. Aluminum is also known as plastic forming, according to aluminum stress during deformation and deformation mode (stress - strain state) is divided into: casting, forging, extrusion, spinning, drawing, rolling, forming (cold, deep drawing) three pattern aluminum and other processing methods, the three pattern aluminum Which is good , rolls supplied by Alcoa Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co.
