  • WORKPIECE HAVING GLOSSY COATING LAYER
    Publication number: 20130280553
    Abstract: A workpiece has a glossy coating layer disposed thereon. A barrel plating device is electrified with an alternating current, which has a voltage between 1V and 100V, a current density between 0.02 A/dm2 and 50 A/dm2, and a frequency between 1 Hz to 60 KHz. The alternating current is rectified by a low ripple DC rectifier into a direct current whose ripple coefficient is between 0.3% and 26%. Thereby, a surface of the workpiece is electroplated with the glossy coating layer, which contributes to a glossy and even effect on the surface of the workpiece.
