3. The specific process of aluminum wheel electroplating process is as follows:
Pre-treatment line:
1, pre-degreasing — 2, degreasing —-3, hot water washing —-4, hot-water washing —-5, pickling—-6, water-washing—-7, water-washing— 8. Passivation—9, deionized water wash—10, deionized water wash—11, closed—12, deionized water wash—13, deionized water wash—hot air dry– -Drying—Transfer to spraying line
Base powder spraying line:
1. Electrostatic dust removal – 2. Base powder spraying – 3. Robot transfer line – 4. Drying – 5. Forced cooling – 6. Online polishing – 7 .Manual transfer
Painting line:
