The classification of brushed metal surface treatment, you will suddenly realize after reading this article.

The metal wire drawing process is a surface treatment process that uses friction to scrape aluminum or aluminum alloy plates out of lines. Because of its unique personality and aesthetic appearance characteristics, it is widely used in decoration and electronic products. The main process of the metal wire drawing process is divided into three steps: deesterification, sand milling, and water washing. The special coating technology after anodization can generate a coating layer containing the metal component on the metal surface, so that each fine The silk marks are clearly visible, so that the metal has a fine hairline luster in the matte.

Straight wire drawing process 

The straight-grain wire drawing process is the most common metal wire drawing process. It is a process that uses mechanical processing to process straight lines on the surface of the aluminum plate.

Swirl wire drawing process

Swirl is also called optical rotation. This process is obtained by installing cylindrical felt or grind nylon wheels on a drilling machine, blending the polishing paste with kerosene, and rotating and polishing the surface of aluminum or aluminum alloy plates. Swirl drawing is mostly used for decorative processing of round signs and small decorative dials.

Random wire drawing process

The chaotic wire drawing process is to make the aluminum plate move forward, backward, left and right under the brush grinding of the high-speed copper wire brush, and rub against the copper wire brush. This processing technology has a higher demand on the surface of the aluminum or aluminum alloy plate.
