Process characteristics:
The Pearl River Delta non-alkaline pre-copper plating is a new generation of copper-free pre-plating process developed by our company with the introduction of foreign technology. Its characteristics are as follows:
It is not necessary and is very suitable for steel parts and brass parts. , aluminum alloy, and zinc alloy workpieces are used as bottom electroplating with strong adhesion
The plating solution is stable and reliable and has a long service life
The plating solution has strong activity and a large cathodic polarization potential. The coating can be thickened, has high brightness and is not brittle
Wastewater It is easy to handle and only needs to add precipitant to remove organic matter and reach the standard emission.

Preparation of plating solution
(
Rack plating takes
as an example
)
Add deionized water to the plating tank and add the solution (containing copper) and stir.
Use % solution adjustment to control the solution value.
Add brightener and stir. Add deionized water to reach the working volume and stir evenly.
Heat to working temperature for trial plating.
