The surface treatment of aluminum profiles is one of the important links in the production of aluminum doors and windows. Good surface treatment can greatly improve the corrosion resistance, weather resistance and service life of aluminum doors and windows.
Of course, the processing technology is different, and the process is also quite different. Today, we will introduce three common surface treatment technologies for aluminum doors and windows: anodizing, electrophoretic spraying, and wood grain transfer.
Electrophoretic spraying
Electrophoretic paint film has the advantages of plump, uniform, flat and smooth coating.
The hardness, adhesion, corrosion resistance, impact performance and penetration performance of the electrophoretic paint film are obviously better than other coating processes.
It has high metal texture, high corrosion resistance and high weather resistance, which is more decorative than spray painting and powder spraying, and is deeply loved by consumers.
Anodizing
Overcome the defects of aluminum alloy surface hardness and wear resistance.
Anodized aluminum profile, anti-static, easy to clean without vacuuming, excellent heat dissipation, super metal appearance, high-grade and beautiful, uniform color, no fading, effectively improve the bonding force of organic coating and inorganic coating .
