Surface treatment of aluminum alloy stamping products – stamping plant
Aluminum alloy stamping products are widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Aluminum alloy is widely used because of its low density, high strength, good plasticity, strong conductivity and good mechanical properties. In order to make the workpiece more beautiful and improve other performance, customers usually require surface treatment.
The common surface treatment of aluminum alloy stamping products are: polishing treatment, the role of polishing is to make the surface of aluminum workpiece close to the mirror effect, can improve the quality of the workpiece and aesthetic effect. However, the surface properties of polished aluminum parts are relatively low and easy to be scratched.
Sand blasting treatment: the function of sand blasting is to make the surface more smooth, make the aluminum parts more beautiful and precise, also can improve the performance of the workpiece and increase the adhesion between the workpiece and the coating.
The function of aluminum anodizing treatment is to improve the wear resistance and hardness of aluminum parts, and various surface colors can be obtained by anodizing.
Drawing treatment, drawing is mainly for decorative effect, common types of drawing are: straight line drawing, random drawing, rotary drawing, thread drawing.
