Detailed Process for Bronze copper plating
Background technique:
Compared with metal parts, plastic electroplated products can not only achieve a good metal texture, but also reduce the weight of the product. While effectively improving the appearance and decoration of the plastic, it also improves its electrical, thermal and corrosion resistance. Performance, improve the mechanical strength of its surface. The existing red bronze electroplating process is complicated, the electroplating process has poor environmental protection performance, and the electroplating effect is poor.
Technical realization elements:
The purpose of the present invention is to provide a red bronze electroplating process to solve the problems raised in the background art.
In order to achieve the above object, the present invention provides the following technical solution: a red bronze electroplating process, including the following steps:
A. Blank inspection;
B. Hang up;
C. Hot-dip ultrasonic wax removal: Put the blank into an ultrasonic machine for ultrasonic, the ultrasonic power is 300W-600W;
D. One-time cleaning: Put the sonicated blank into deionized water for rinsing, and the rinsing time is 10min-20min;
E. Hot-dip ultrasonic degreasing: Put the cleaned blank into the ultrasonic machine again for ultrasonic, the ultrasonic power is 1000W-1500W;
F. Secondary cleaning: Put the ultrasonic blank into deionized water for rinsing, and the rinsing time is 10min-20min;
G. Acid activation: Put the blank into the activation tank, which contains acid activator, the content of activator is 20%-30%; the temperature in the activation tank is 35℃-45℃, and the activation time is 20min-30min;
H. Three times of cleaning: Put the activated workpiece into deionized water to rinse, and the rinse time is 5min-10min;
I. Cyanide activation: Put the cleaned work piece into an activation tank, the activation tank contains cyanide activator, the activator content is 15%-25%; the temperature in the activation tank is 45℃-50℃, and the activation time is 10min- 20min;
J. Pre-plating copper bath: the workpiece after cyanide activation is processed in the pre-plating copper bath;
K. Four times of cleaning: Put the workpiece in the pre-copper plating tank into deionized water for rinsing, and the rinsing time is 5min-10min;
L. Copper pyrophosphate tank: treat the cleaned workpieces in a copper pyrophosphate tank;
M. Five times of cleaning: Put the workpiece after the copper pyrophosphate tank into deionized water for rinsing, and the rinsing time is 5min-10min;
N. Acid copper tank: Treat the cleaned workpieces in an acid copper tank;
O. Six times of cleaning: Put the processed workpiece in the acid copper tank into deionized water for rinsing, and the rinsing time is 5min-10min;
P. Gun black slot: the cleaned workpiece will be treated with gun black slot;
Q. Passivation: passivate the workpiece after the gun black slot is processed;
R. Drying: Put the passivated workpiece into an oven at 200℃-300℃ for drying treatment, and the drying time is 30min-50min.
