5: Electro plating producing flow chart.
Different galvanization procession is different.
But there are some basic process in common.
A: Firstly, oil remove.
There is oil when you have a handle out from a die casting process, such as zinc die casting.
We need to remove oil firstly, otherwise the electro-plating coat is easy to fall off.
