Aluminum alloy processed parts generally require anti-oxidation treatment after processing. Otherwise, mold dust will appear on the surface after being left for a period of time, which is oxidation powder. General anti-oxidation treatments include: chromium passivation, anodizing, chemical oxidation, etc. We also have antioxidant products that are neutral, environmentally friendly, and easy to use.
If the process requires spray painting, plastic spraying, electrophoresis or electroplating, the surface treatment methods are different.
