The six most common metal surface treatment processes

Aluminum alloy surface treatment process that you don’t know?

1. Aluminum alloy surface drawing treatment process.
Under the action of external force, the technical processing method of forcibly compressing the metal through the metal cross-sectional area of the mold to obtain the shape and size of the required cross-sectional area can change the existing mechanical pattern or surface deficiency, and eliminate mechanical gate and clamping defects in production. Regular and relatively uniform new textures can be made to achieve a silk satin-like decorative effect.

2. Metal surface embossing treatment process.
Aluminum metal plate embossing (also called bite pattern) is embossed on the metal plate by mechanical equipment to make the surface of the plate produce concave and convex patterns, most of which are used to improve the product experience.

3. Aluminum alloy surface sand blasting treatment process.
Sand blasting uses compressed air as the power to form a high-speed jet beam to spray the spray material at high speed to the surface of the workpiece to be treated, thereby changing the surface or shape of the workpiece. It can improve the mechanical properties of aluminum alloy to a certain extent, making it more delicate.

4. Aluminum alloy surface polishing treatment process.
Polishing is a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It can also be used to eliminate gloss, including mechanical, electrolytic, chemical and nano. When you see a bright surface in the future, don’t immediately think it is electroplating, it may be polishing.

5. Aluminum alloy surface water transfer printing treatment process.
Everyone generally uses silk screen printing or pad printing more, which is generally suitable for text or patterns with a small area. If the surface contains large-area patterns, water transfer printing uses water as the dissolving medium. Colored pattern board/full printing film is used for printing of graphic transmission.

6. Aluminum alloy etching surface treatment process.
Through exposure plate making, after development, remove the protective film on the pattern area to be etched, and contact with the chemical solution during metal etching to play the role of dissolution and corrosion. Forming the effect of unevenness or punching, the texture or graphics of many aluminum plates are often made by etching.
