Common Metal surface treatment process
Powder Coating
Dry powder is electrostatically applied to the metal surface and then cured under high temperature to form a hard and durable surface.
Galvanizing
Coating a metal surface with a layer of zinc to protect it from corrosion.
Mirror polishing
Polishing can make the metal present a different glossiness, which can enhance the metal material effect.
Wire drawing
By mechanical or chemical methods, it creates a fine texture on the metal surface to increase the texture and decorative nature of the metal surface.
Anodizing
The surface of aluminum alloy is treated by electrochemical oxidation to form an oxide film of uniform thickness to increase its corrosion resistance and decorative properties, commonly used in electronic products, construction materials, etc.
Black oxide coating
Through chemical reaction, the metal surface is oxidized to form a black oxide film to increase its corrosion resistance and decorative properties, commonly used in the surface treatment of automobiles, motorcycles, weapons, etc.
Electroplating
The metal surface treatment is immersed in electrolytic solution to form a metal film through electrochemical reaction to increase its corrosion resistance and decorative properties, commonly used for surface treatment of automobiles, furniture, tableware, etc.
Sandblasting
By blasting abrasives at high speed, the metal surface is processed into a frosted effect to increase its texture and decorativeness.
Laser Engraving
Laser beam is used to engrave and carve the metal surface.
Paint spraying
Paint or coating is uniformly sprayed onto a metal surface through a high-pressure spray gun to achieve protection, beautification, and decoration.
Pad printing
Transferring a pattern or text from a print to a metal surface.
Screen Printing
Printing a pattern or text on a metal surface by applying ink to the mesh.
QC process
Inspection of the metal surface
The metal surface is thoroughly inspected to ensure that it is clean and free of any contaminants that could interfere with the process.
Control of process parameters
Careful control of the surface treatment involves a series of steps to ensure that the treatment is correct and consistent.
Monitoring of the quality of the treatment
The quality of the treatment is monitored to ensure that it meets the required specifications.
Post-treatment inspection
Re-inspection of the metal surface to ensure that the treatment is correct and of the required quality to the required specifications.
