Our Company is offering the following Electro-plating services such as Passivation, Barrel Polishing, Electroless Nickel Plating for aluminum, brass and steel, Electro-Deposition for aluminum and steel, Chromating, annealing, Copper Nickel Barrel Plating and so on.
I want is to provide me information on how to prevent the following problem:

- 2. No Coat
- 3. Deformation
- 4. Dull Appearance
- 5. White Stain
- 6. Rust
- 7. Lot Mixing
- 2. No Coat

I am having the same problems with my plating processes, especially white stain. Have you came up with the solution to prevent this issue from happening?

(Full name next time, please, Charn; this isn't an anonymous service). Plating is very complex, and it would take a whole finishing library to describe the most likely causes for a wide variety of defects across a number of finishing processes. But Larry Durney's "Trouble In Your Tank" is perhaps the shortest route to those answers. Good luck.
