Six unique processes of aluminium sheet surface treatment (1)

As aluminium and aluminium alloy products become more and more widespread into our lives, we all demand higher and higher quality of aluminium alloy products. What kind of products can attract more users? Then we have to work on the visual effect and surface treatment of aluminium alloy products. Let our experts explain to you in detail the six unique processes of aluminium alloy surface treatment.

Unique process one: sandblasting (shot blasting)

The process of cleaning and roughening the metal surface using the impact of high-speed sand streams. This method of aluminum surface treatment can make the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, therefore improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating film, but also conducive to the leveling and decoration of the coating. This process is often seen in various Apple products and is increasingly being used on existing TV cases or frames.

Unique process two: polishing

The use of mechanical, chemical or electrochemical methods to reduce the surface roughness of the workpiece, in order to obtain a bright, flat surface processing methods. Polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing. Aluminium parts using mechanical polishing + electrolytic polishing can be close to the mirror effect of stainless steel, giving a high-grade simple, fashionable future feeling (of course, easy to leave fingerprints and more care).

Unique process three: brushing

Brushed metal is the manufacturing process of repeatedly scraping lines out of aluminium sheets with sandpaper. The drawing can be divided into straight drawing, messy drawing, rotary drawing and thread drawing. Metal processing micro letter, the content is good, worthy of attention. The brushed metal process, which clearly reveals each and every microscopic wire mark, gives the metal a fine hairline sheen in a matt finish, making the product both stylish and technological.
