1.Sand blasting

The process of cleaning and roughening the metal surface by the impact of high-speed sand flow. This method of aluminum surface treatment can make the surface of the workpiece a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, so the fatigue resistance of the workpiece is increased, and the distance between it and the coating is increased. The adhesion improves the durability of the coating film and is also conducive to the leveling and decoration of the coating. The aluminum alloy process we often see in Apple's various products, and is more and more used in the existing TV case or middle frame.


2. Polishing
A mechanical, chemical or electrochemical method is used to reduce the surface roughness of automotive aluminum parts to obtain a bright and flat surface processing method. The polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing.


3. Silk Screen
Metal wire drawing is a manufacturing process that repeatedly scratches aluminum plates 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.
