1. polishing refers to the use of mechanical, chemical or electrochemical action, to reduce the surface roughness of the workpiece in order to obtain a bright, smooth surface processing method.
2. the general brand big factory will use ultrasonic cleaning machine using ultrasonic cleaning, the glasses shop cleaning technology is the same, high cleanliness.
3. oxidation this step is to make the product more wear-resistant, brand big factory will be oxidized to the product
4. specular is the product of the excuse for a high degree of polishing, brand large factory will purchase higher quality import specular machine, so specular interface is generally more uniform.
5. Laser brands generally use high-quality laser to carve the logo onto the products.
6. paste accessories brand big factory will use special appliances, the internal part of the pressure to the inside of the shell.
The metal surface oxidation treatment methods are as follows:
Electrophoresis, also known as electric paint, was first applied to automotive primers by the ford motor company in the 1960s. Because of its excellent anti-corrosion and anti-rust functions, it was soon widely used in the military industry. In recent years, it has been applied to the surface treatment of daily hardware. Advantages: no metal texture, can cooperate with sandblasting, polishing, wire drawing; The surface treatment of complex structure can be realized by processing in liquid environment.
Anodic oxidation is mainly anodic oxidation of aluminum, which is to generate a layer of aluminum oxide film on the surface of aluminum and aluminum alloy by means of electrochemical principle. This oxide film has protective, decorative, insulating, wear resistance and other special characteristics. Advantages: achieve any color except white; Achieve nickel – free hole sealing, to meet the European, the United States and other countries on nickel – free requirements.
