why 1.电镀后挂钩接触部位镀层偏高或者产生轻微毛刺（挂钩接触位置(

why 1. hook contact points after plating or coating the high slight burr (hook contact position (opening portion) current is too large, the effect of strong adsorption of the coating, the coating than other parts of the uneven thickness);

why 1. The coating of the contact area of the hook after electroplating is high or produces a slight burr (the contact position (mouth) of the hook is too large, the coating adsorption effect is strong, thicker than the coating of other parts);

After electroplating, the coating on the contact part of the hook is too high or produces slight burr (the current at the contact position (mouth) of the hook is too large, the coating has strong adsorption effect, and the coating on the other parts is too thick);<br>
