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

1. Sandblasting: The main function is surface cleaning. Pre-sandblasting can increase the surface roughness, which is good for improving adhesion. Sandblasting can be divided into coarse sand and fine sand. The commonly used ones are 120 mesh and 100 mesh.

2. Conductive oxidation: Aluminum parts have certain anti-corrosion and conductivity after conductive oxidation. They are often used in prototypes of electronic equipment. Conductive oxidation of aluminum can prevent the interference of electromagnetic signals.

3. Anodizing: Anodizing is a method that uses the principle of electrolysis to form an oxide film on the surface of the prototype to increase 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 plastic powder through high-voltage electrostatic equipment. Under the action of the electric field, the paint is sprayed onto the surface of the workpiece. The powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating.

5. Electroplating: Use the workpiece as the cathode and the material forming the coating as the anode. Place both in a tank with plating solution, and then pass direct current or alternating current to ionize the material forming the coating and remove it from the plating solution. A method of running towards the surface of the workpiece and firmly attaching to it to form coatings of different thicknesses.

Aluminum alloy prototypes are mostly used for anodizing (mostly natural oxidation), plastic spraying (rich in color, high quality and low price, the most commonly used), electrophoresis (mainly shiny K gold, K silver, champagne color) , Thermal transfer printing (mainly wood grain transfer printing, which shows the wood texture and looks good).

The surface treatment of aluminum alloy prototypes is to enhance the surface hardness and wear resistance of aluminum alloys, expand its application range, and extend its service life. Surface treatment has become an indispensable part of the use of aluminum alloys, and anodizing is the current application of aluminum alloy prototypes. common.
