Electroplating Rectifier

GKDMZ NC Double-pulse Electroplating Power Supply, also called Periodic Reversal Double-pulse Plating Power Supply is made by our company which used the advanced power technology that based on the trends of electroplating technology.
This series of power especially apply to gold-plating, silver-plating, nickel-plating, iron-plating, stannum-plating, and alloy-plating etc; The deposited energy of electrolytic condenser; The electroplating of copper and nickel; The anode oxidation of aluminum and titanium products and the holes' metalizing of micro-holes, long holes, and blind holes during the production of the printed circuit board.
GKDM can let the coating more informing, compact, light, and the poriness more low, the purity and density more high. Also, it can further improve the heat-proof, wear-proof, corrosion prevention, toughness and electric conductivity etc., and it can substantially save the precious metal (about 20-50%), and the additive (about50-80%). The series of GKDM is an ideal equipment that can increase production and improve the quality of product.
Function Features:
The devices have the same properities of two single pulse power. The frequency of the positive or negative pulse, the duty ratio, the on and off time of pulse, the output amplitude can be adjusted separately. There's no influence on each other.
The main function of the devices output the current is millisecond, positive or negative periodic reversing. A machine serves several purposes with the output function of pure DC and pulse. The output can be chosen to be positive or negative pulse; Pulse or current, or DC superimposed pulse(reversing). And it can be used as two single pulse or pure DC power at the same time.
It has multiple protection function of short circuit, overload, overcurrent, overvoltage, overheat etc.
The electric contact of the complete machine is preservative and highly reliability.
Advantages of the Products:
It reduces concentration polarization and increase the current density of negative pole. It gets a coating which with compact, uniformity and high electric conductivity.
Reverse-pulsing obviously change the coating's distribution of thickness and also to be leveled because it dissolved the burr on the negative pole coating.
Reverse-pulsing dissolved the spare coating on the negative pole which makes the purity of metal ion nearby the negative pole can recovery rapidly. It can benefit the following distribution of current density on coating which is driven by direct pulse and high pulse current density makes the formation of nucleating faster; So the crystalloid coating can be more detailed, shiny.
It can eliminate the hydrogen embrittlement, reduce the physical properties of coating, and increase the toughness of coating.
Reverse-pulsing can remove the deposited hydrogen. It reduces the hydrogen content in coating and effectively eliminates or reduces the internal stress.
Reverse-pulsing can activate the surface of negative pole and improve the brand of coating. It can also reduce the impurity content of coating and increase the purity of it.
