Do you know the surface treatment of aluminum alloy hand plate?
Release time:2022-08-15

What kind of surface treatment does the aluminum alloy hand plate have? After the aluminum alloy hand plate is processed by CNC, it needs a series of surface treatments to obtain a bright and beautiful hand plate model. So what are the surface treatment effects of aluminum alloy hand plate? Next, we will have a brief introduction from Bohao processing factory.

1. Sand blasting: mainly used to clean the surface. Frontal sandblasting can increase surface roughness and improve adhesion. Sand blasting can be divided into coarse sand and fine sand. 120 mesh and 100 mesh are commonly used.

2. Conductive oxidation: the conductive oxidation of aluminum parts has certain corrosion resistance and conductivity, and electronic equipment prototypes are used more. After the conductive oxidation of aluminum, the interference of electromagnetic signals can be avoided.

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

4. Plastic spraying: also known as electrostatic powder spraying, the advantages of this technology are reflected in advanced technology, energy saving, high efficiency, safety and reliability, bright color, etc. Its working principle is that the plastic powder is charged by the high-voltage electrostatic device. Under the action of the electric field, the paint is sprayed onto the surface of the workpiece, and the powder will be evenly adsorbed on the surface of the workpiece. The workpiece forms a powder coating.

5. Electroplating: take the workpiece as the cathode and the material forming the coating as the anode, and place them in the tank containing the plating solution. Then apply DC or AC / DC current to ionize the material to form the coating and remove it from the plating solution. A method of running to the surface of a workpiece and firmly adhering thereto to form layers of different thicknesses.

Aluminum alloy prototypes are mostly anodized (mostly natural oxidation), plastic sprayed (rich in color, high quality and low price, and most used), electrophoretic (mainly shiny K gold, K silver, champagne color), and thermal transfer (mainly wood grain) transfer printing, presenting wood texture and good-looking.

The surface treatment of aluminum alloy prototype is to improve 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 of the use of aluminum alloys, and anodizing is a common application of aluminum alloy prototypes.
