1. It is well known that alloy wheels plating involves complex process, using a variety of brighteners, additives, so the finished product——plating alloy wheels are the sign of enterprise level. With the rapid plating development of alloy wheels industry, the plating production will increase significantly. According to incomplete statistics, currently there is more than 30 appliances alloy wheel business.
2. The process of alloy wheels plating
2.1 Pre-treatment in plating alloy wheels
Blank inspection – mechanical polishing – cleaning – drying – test – send plating
2.2 Dip Galvanizing
Inspection – before treatment – cleaning – alkaline corrosion – Cleaning – Cleaning – dip zinc – Cleaning – back zinc – Cleaning – dip zinc – Cleaning – Cleaning
2.3 Plating copper in alloy wheels
Pre-nickel – Cleaning – activation – Acid Copper
2.4 Plating Nickel Chromium
Polishing – before treatment – Cleaning – activation – Degreasing – Semi bright nickel plating – nickel-plated high sulfur – bright nickel plating – chrome plating – test
3. Specific procedures of alloy wheels plating are as follows
Pre-treatment Line: 1, pre-fat — 2, degreasing — 3, washing with hot water — 4, washing with hot water — 5, washing wit acid — 6, washing with water— 7, washing with water — 8, passivation — 9, deionized water washing — 10, deionized water washing — 11, closed — 12, deionized water washing — 13, hot deionized water washing — dry – - transfer coating line drying.
Powder coating line at the end of alloy wheels: 1, electrostatic dust — 2, powder coating — 3, robotic transfer lines — 4, drying — 5, strong cold — 6, online polish — 7, artificial transfer line.
Painting line on the alloy wheels: 1, electrostatic dust — 2 primer coating — 3, spray robot fill — 4, flash dry — 5, lacquer coating — 6, spray robot fill — 7, leveling — 8, robot lane changing — 9, drying — 10, strong cold — 11, artificial transfer line
Glitter spray line of alloy wheels: 1, electrostatic dust — 2, glitter spray — 3, robotic transfer lines — 4 drying — 5, strong cold — 6, manual transfer line.
