How to oxidize the aluminum alloy prototype model


News Dec 10 2019

Our company is a precision prototype manufacturer in Shenzhen, China, which specializes in manufacturing prototype models. Our hardware prototypes, such as aluminum alloy prototypes, are reliable and affordable. Let us take a look at the manufacturing process and precautions of aluminum alloy prototype.
Most of the aluminum alloy hand plates are CNC processed. According to the customer's drawings, then CNC processing is performed, and finally a series of surface treatments, and of course, oxidation treatment, become the final aluminum alloy hand plates. The aluminum alloy prototype model is one of the most common metal prototype models. The surface treatment is usually oxidation. What oxidation? Why do we need oxidation? What precautions need to be taken during oxidation?

Oxidation treatment of aluminum alloy hand plate: Oxidation treatment is to harden the surface of aluminum to form a film, so that the finished product is not easy to scratch. The purpose of aluminum alloy hand plate oxidation is two main: one is to prevent the hand plate The surface is corroded. The second is to improve the aesthetics of the hand. After the slab has been oxidized, it is also equipped with the corresponding subsequent surface treatments such as oil injection, wire drawing, and sand blasting, which not only can make the surface of the product beautiful, improve the grade of the product, but also extend the service life of the product.
Aluminum alloy hand plate oxidation is a commonly used technology for surface treatment of aluminum alloy hand plates, but sand blasting is usually required before oxidation, otherwise it will affect the aesthetics of aluminum alloy hand plates; if the surface of aluminum alloy hand plates is polished, it will be deoxidized. If the aluminum alloy hand board you want to make is natural, just sand it and then sandblast it.

There are a lot of precautions when processing the aluminum alloy hand plate. The following explains the issues that need to be paid attention to before sandblasting:
Before sandblasting the aluminum alloy, the sand type and particle size must be selected.
The blasting should be uniform: the blasting pressure should be consistent, the nozzle should move smoothly, and the spraying angle should be the same. Do not shoot directly at the part and close the gun; the distance between the nozzle and the workpiece must be consistent.
After sand blasting, it undergoes alkali etching—chemical polishing—anodizing—sealing—drying.
