Six Surfaces Treatment Methods of aluminum profiles

This material has existed in life for a long time, but in recent years it has played tricks through the application of high-tech products, and has become a representative of Gao Fushuai. Especially in the recent years of mobile phone design, Apple, Samsung, Meizu, Xiaomi, Huawei, etc. have made great efforts in the use of materials and machining technology. Today we introduce the various machining methods of this material!
 
  Because of its easy machining, good visual effects, and rich surface treatment methods, aluminum is first used by various manufacturers. The surface treatment of aluminum profiles is mainly divided into: sandblasting (form matte pearl silver surface), polishing (form mirror surface), and wire drawing ( Form a satin-like effect), electroplating (covering a layer of other metal), spray coating (covering other non-metallic coatings).
   1. Sandblasting
    Sand blasting uses compressed air as the power to form a high-speed jet beam to spray the blasting material (copper ore sand, quartz sand, corundum, iron sand, sea sand) on the surface of the workpiece to be processed at high speed, so that the appearance or shape of the workpiece surface changes. Sand blasting has strong applications in engineering and surface technology, such as: increasing the viscosity of adhesive parts, decontamination, optimizing surface burrs after machining, and surface matte treatment.
    The sand blasting process is more uniform and efficient than manual sanding. The stainless steel treatment of this method creates the low-key and durable characteristics of the product.
   2. polishing
    The polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing.
    The machining aluminum parts can be close to the stainless steel mirror effect after mechanical polishing + electrolytic polishing, giving people a sense of high-end simplicity and stylish future.
    3. drawing
    Metal wire drawing is the manufacturing process of repeatedly scraping the aluminum plate out of the line with sandpaper. Drawing can be divided into straight drawing, random drawing, spiral drawing, thread drawing.
    The metal wire drawing process can clearly show each tiny silk mark, so that the metal matte has a fine hair shine, and the product has both fashion and technology sense.
   4. highlight cutting
    A diamond engraving machine is used to strengthen the diamond knife on the high-speed rotating (generally 20,000 rpm) spindle of the engraving machine to cut parts, creating local highlight areas on the product surface. The brightness of the cutting highlight is affected by the speed of the milling drill. The faster the drill speed, the brighter the cutting highlight, otherwise the darker and prone to cutting.
    High-gloss high-gloss cutting is particularly used in mobile phones, such as iphone5. In recent years, some high-end TVs have adopted high-gloss milling technology on the metal frame. In addition, anodizing and wire drawing have made the TV as a whole full of fashion and technology.
  5.Anodizing
    Anodizing services refers to the electrochemical oxidation of metals or alloys. Under the corresponding electrolyte and specific process conditions, aluminum and its alloys form an oxide film on aluminum products (anode) due to the applied current. Anodizing can not only solve the defects of aluminum surface hardness and abrasion resistance, but also extend the service life of aluminum and enhance the aesthetics.It has become an indispensable part of aluminum surface treatment and is currently the most widely used and very successful. Craft.
    6. two-color anodizing
    Two-color anodizing refers to anodizing on a product and giving different areas a different color. Two-color anodizing is more complicated and costly because of the complicated process. However, the contrast between the two colors can better reflect the high-end and unique appearance of the product.
