What are the ways of surface treatment of mechanical keyboard aluminum shell?

 

Mechanical keyboard aluminum shell surface treatment methods are various, designed to enhance the beauty of the product, corrosion resistance and durability. The following are several common surface treatments:

 

Anodizing:

This is an electrochemical process that increases hardness and corrosion resistance by forming an alumina film on the surface of aluminum. Anodizing not only enhances the durability of the material, but also allows a variety of color effects to be achieved through dyeing technology, making the product more beautiful.

Sandblasting:

Sandblasting is the use of high-speed flow of abrasive particles to impact and cut the aluminum surface to achieve uniform roughness and flatness. This method can make the aluminum surface get matte or semi-matte effect, while removing small surface defects.

Polishing:

The polishing process can make the surface of aluminum products smooth and shiny, divided into mechanical polishing and chemical polishing. It can enhance the gloss and visual appeal of the product, but it should be noted that the polished product may be more prone to scratches if it is not further protected.

Powder Coating:

Powder spraying is a dry coating technique in which powder coating is attached to the surface of the workpiece using static electricity and then heated to melt it to form a strong and continuous coating. This method provides a rich choice of colors, and has good wear and weather resistance.

Brushing:

Drawing is the process of creating a fine, even line texture on the surface of aluminum, which is often used to create a high-end texture. This treatment not only increases the beauty, but also provides a certain degree of anti-slip function.

Laser Engraving:

High energy density laser beams are used to write words or patterns on aluminum surfaces. Laser engraving can not only achieve very fine design, but also ensure that the color will not fade for a long time.

These surface treatments can be used alone or in combination to select the most suitable method according to different design requirements and expected effects. Each processing method has its own unique advantages and can meet the needs of different users for the appearance and performance of mechanical keyboards.
