Due to the high temperature of the plating solution, the evaporation of the bath solution, the volatilization of the chromium mist and the bringing out of the workpiece when out of the bath, the liquid level drops. When the distance between the upper part and the liquid level is less than 5mm, the power line distribution is abnormal. During electroplating, the current density of the upper part is insufficient, resulting in the small coating.
