How to Custom CNC Machining Aluminum Mobile Phone Case?

Speaking of mobile phones, it can be said that they are indispensable items in life. They play an important role in daily life. With the rapid development of mobile smart technology, there are various functions on mobile phones, such as watching TV dramas, online games, office work, and repairing. Pictures, etc. can be achieved through mobile phones. Even without shyness, mobile phones have become the most important tool in our lives, and more and more people cannot do without mobile phone case. As a communication tool, mobile phones have become more and more powerful, and their mobile phone shell production technology has become more and more high-end.

The diversity of metal materials of the mobile phone case makes it look more high-end and more textured in appearance. It is often favored by the public, but do you know about metal phone cases? How does it achieve the appearance of texture? Want to know more about how the surface treatment of mobile phone shells is done? Then you must read this article.

What material can be made of the custom CNC machining aluminum mobile phone case?

In terms of practicality, our commonly used metal materials include magnesium, aluminum, stainless steel and other alloy materials. These materials not only have the function of heat resistance and heat conduction, but also have good electromagnetic shielding and internal protection. They are dimensionally stable in appearance, Beautiful features. For example: i Phone5s mobile phone shell uses a combination of metal and glass, and the metal part (that is, the back metal shell) is made of aluminum alloy.

In addition to the commonly used metal materials, the material of the phone case also includes industrial plastics such as PC/ABS/PMMA.

Brief introduction of custom CNC machining aluminum mobile phone case production process:

Panel-oil spray-silk screen-pad printing-laser-electroplating-wire drawing-high gloss-UV-relief-CNC lathe machining-CNC milling processing-sandblasting-paste printing and so on.

The oxidation process of the custom CNC machining aluminum mobile phone case is completed by a certain chemical effect. The surface of the material used for the production is oxidized to form a layer of film to improve the practicability of the product, such as corrosiveness, reflectivity, wear resistance and usability, etc. Increase beauty and other effects.

For mobile phone cases made of aluminum/aluminum alloys, anodizing technology is widely used.
 

Anodic oxidation process of custom CNC machining custom CNC machining aluminum mobile phone case

The principle of anodic oxidation is that hydrogen is deposited on the cathode through electric current; oxygen (including oxygen, atomic oxygen and ionic oxygen) is deposited on the anode. The aluminum as the anode is oxidized by the precipitated oxygen, thus forming an aluminum oxide film on the surface.

Anodizing process

1. Preliminary treatment:

a. Degreasing: Used to remove grease and grease on the surface of custom CNC machining custom CNC machining aluminum mobile phone cases.

b. Alkaline washing and push plating: used to remove the old oxide layer on the surface of the custom CNC machining custom CNC machining aluminum mobile phone case to expose the pure substrate.

c. Acid-eluting film: Acid-eluting film: used to remove the black water film and dirt on the surface of the custom CNC machining custom CNC machining aluminum mobile phone case, and the uniformity/thickness/brightness of the surface material of the shell can be adjusted.

d. Polishing: Used to eliminate mechanical defects on the surface of aluminum mobile phone casings, reduce surface roughness, and improve its surface gloss. Usually phosphoric acid is used for treatment.

2. Anodizing: The process of using aluminum or aluminum alloy products as anodes in an electrolyte solution, and using electrolysis to form an aluminum oxide film on the surface.

3. Post-processing:

a. Activation: used to expand the hole, increase the porosity, and improve the dye adsorption effect in the next process.

b. Dyeing: According to customer requirements, produce custom CNC machining aluminum mobile phone cases with beautiful colors and appearances.

c. Hole sealing: improve the quality and dyeing firmness of the custom CNC machining aluminum mobile phone case, prevent the appearance of magnesium oxide from deforming, and make the custom CNC machining aluminum mobile phone case have the ability to prevent fingerprints, stains and grease stains.

d.Drying: The process in which the ink is transformed into a solid film due to oxidative polymerization.

The above is the process of customizing CNC machining aluminum alloy mobile phone case, I hope it will be helpful to you.
