Electroplating of Metal Label

Metal label are widely used in electronic products, home appliances, machinery and civil products and handbag accessories. The production of metal label is mainly based on copper, iron, aluminum, zinc alloy, titanium, stainless steel and other raw materials, through stamping, die-casting, etching, printing, enamel, imitation enamel, baking paint, dripping, electroplating and other processes. However, in the process of making metal signs, it is also important to master a good electroplating method.

What are the electroplating methods for metal signs? The details are as follows:
(1) Drill a small hole in the place reserved for the semi-finished product of the metal sign, tie the copper wire through a small section through the small hole, and leave enough length at the other end;
(2) Put the semi-finished metal sign with laser shading into the degreasing solution, tie the copper wire at the upper end to the copper tube, make the copper wire fully contact with the copper tube to ensure good electrical conductivity, and set the temperature to 58 degrees, Adjust the time to 300 seconds, set the current to 10 amps, remove the semi-finished product with the laser shading, and rinse it in distilled water;
(3) Put the semi-finished laser shading metal sign after electrolytic deoiling into nickel chloride solution, set the temperature to 25 degrees, the time to 300 seconds, the current to be 10 amps, and rinse it in distilled water;
(4) Put the nickel-plated semi-finished metal sign with laser shading into the cupric chloride solution, set the temperature to 28 degrees, the time to 300 seconds, the current to be 10 amps, and rinse it in distilled water;
(5) Put the copper-plated semi-finished metal sign with laser shading into the silver nitrate solution, set the temperature to 58 degrees, the time to 300 seconds, the current to be 10 amps, and rinse it in distilled water;
(6) Put a conductive clip on the copper wire of the semi-finished metal sign with laser shading, and then put the semi-finished metal sign with laser shading into the solution of potassium gold cyanide, set the temperature to 52 degrees, and the time to 30 seconds. The current was 5 amps, the silver-plated metal sign was swung back and forth in the solution, and finally it was removed and rinsed in distilled water.
