Summary of surface technology of aluminum box

With the continuous prosperity of the aluminum box market, the aluminum box surface technology market also develops, some new technologies are constantly applied in the surface production of aluminum box, and some traditional technologies are constantly innovating to create a variety of processes, making the surface technology of aluminum box more and more diverse, more and more colorful.

However, due to the variety of choices, many aluminum box designers have a hard time deciding among the numerous processes. Here are some of the surface treatment techniques commonly used in making aluminum boxes at Olwin Factory:

1. Anodic oxidation is generally said to remove grease, dust and other impurities on the surface of aluminum plate with strong acid, and then attach color toner (toner and aluminum plate surface produce chemical reaction), and finally close the toner, so as to keep the color brightness and durability.

Overall, anodic oxidation process is a traditional surface of the aluminum production process, after many years of production practice, the technology is already very mature, its stable quality, lower production traveler, a variety of color choices (color can be according to the demand modulation), make the process become the preferred means of aluminum surface treatment.

2. Spray oil on the surface of aluminum box with specific metal paint, and then bake at 180-200 ° C to make the paint adhere to the surface of aluminum.

Oil injection is also a more traditional surface production process. When the number of products is large, oil injection line operation can greatly save the production time and cost.

However, small batch production still depends on manual completion, its color stability and production efficiency is relatively unstable, the use of this process should fully consider the quantity of products.

3. Spray the powder on the surface of the aluminum box and then bake it at a high temperature above 200 ° C to fully melt the color powder. When the temperature naturally drops to room temperature, the color powder will evenly adhere to the surface of the product.

The biggest point of dusting is the color stability, the biggest disadvantage is that the coating is thicker, if it is a more precise size, more complex structure of the product department is recommended to use this process.

4, wire drawing on the aluminum surface with a special wire drawing machine, through the sand belt to pull out the same direction of straight lines.

Drawing effect is divided into a lot of kinds according to the model of different sand belt, there are thick and fine, it is best to choose this kind of process is to customize the width of drawing lines according to the size of their own products, products to show the characteristics, such as the larger products or to show the more rough products, it is best to choose the thicker drawing lines.

5, sand blasting with sand blasting machine will be specific abrasive, high-speed jet to the surface of aluminum, so that it produces a surface uneven effect.

Sand blasting is also divided into coarse sand and fine sand, can be decided according to different needs.

6. Mirror polishing aluminum plate surface is polished to a mirror effect by a special machine.

Generally, products of this process are directly purchased from imported mirror aluminum plate to make the subsequent process. It is not recommended to polish the products after they have been made. In addition, the products of this process are easy to scratch with large loss and high production cost.

7. Surface etch pattern A custom pattern is produced on the surface of aluminum in a corrosive manner.

This process product is also directly customized etched lines of aluminum plate, after coming back to make the subsequent process.

This process costs more, but the surface of the product is beautiful and the etched lines are clearly visible. It is used in many high-end metal CARDS.

Surface bioxyethylene means two times of anodizing. First, the color of the pattern should be shown by oxidation. Then, the pattern should be printed on the surface of the aluminum plate with anti-corrosion ink.

This process produces patterns that do not fade and can appear as bulged, making the product quite upscale, but at roughly twice the price.
