What are the surface treatments of aluminum alloy prototypes? After the aluminum alloy prototype is processed by CNC, it needs to go through a series of surface treatments to get a bright and beautiful prototype model. So what are the surface treatment effects of aluminum alloy prototypes? Next, the Xiehe prototype processing factory will give you a brief introduction.

1. Sand blasting: The main function is to clean the surface. Front sand blasting can increase the surface roughness, which is good for improving adhesion. Sand blasting can be divided into coarse sand and fine sand, and the commonly used ones are 120 mesh and 100 mesh.

2. Conductive oxidation: Conductive oxidation of aluminum parts has certain corrosion resistance and electrical conductivity. There are many prototypes of electronic equipment. Aluminum conductive oxidation can prevent electromagnetic signal interference.

3. Anodizing: Anodizing treatment is a method of forming an oxide film on the surface of the prototype by using the principle of electrolysis to increase the corrosion resistance and make the appearance beautiful.

4. Plastic spraying: also called electrostatic powder spraying, the advantages of this technology are reflected in advanced technology, energy saving and high efficiency, safety and reliability, and bright color. Its working principle is to charge the plastic powder through a high-voltage electrostatic device, and under the action of the electric field, spray the paint onto the surface of the workpiece, and the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating.

5. Electroplating: The workpiece is used as the cathode, the material forming the coating is used as the anode, both are placed in the tank with the electroplating solution, and then a direct current or an alternating current is applied to ionize the material forming the coating and remove it from the electroplating solution. The method of running to the surface of the workpiece and firmly adhering to it to form coatings of different thicknesses.

Aluminum alloy prototypes are mostly used for anodic oxidation (mostly natural color oxidation), plastic spraying (rich colors, high quality and low price, and the most used), electrophoresis (mainly shiny K gold, K silver, champagne) , Thermal transfer printing (mainly wood grain transfer printing, showing wood texture, good-looking).

The surface treatment of aluminum alloy hand plate is to enhance the surface hardness and wear resistance of aluminum alloy, expand its application range, and prolong its service life. Surface treatment has become an indispensable part in the use of aluminum alloy, and anodic oxidation is the current application of aluminum alloy rapid prptotype common.

The above content is the content about the surface treatment of aluminum alloy rapid prptotype introduced by the Xiehe rapid prptotype processing manufacturer. I hope it can be helpful to everyone.
