Hub spraying
Although the appearance of wheel hub spraying is beautiful, the adhesion of spraying is not strong and it is easy to peel off and fade. But this price is cheap.
Hub water electroplating
The adhesion of hub water electroplating is better than that of hub spraying, but once there is a little peeling, the front part will fall off in large pieces, and the color is single, the process is complicated and the price is high.
Hub vacuum plating
Hub vacuum plating has strong adhesion, brighter surface than water plating and strong corrosion resistance. The price is higher than spraying, but cheaper than water plating. Moreover, water electroplating is polluted, and now most of them are spray plating or vacuum electroplating. Moreover, more and more car owners have been inclined to safe vacuum electroplating.
