To design of electroplating project, like plastic electroplating or hard chromium plating, it is need to considerate of use electroplating patent that available on this world. On using this patent we can just request for certain consultant that experience on this project. Electroplating project is an expensive project that we should consider of using money and avoid from fail on the project. Beside of hire of consultant on the project, we also can recruit of experience people on this area field. But experience people sometime we can't guarantee of their knowledge of whole understanding of the process, many experience people just mastery on using certain equipment but don't know the process philosophic.
The example of some patent that sold on the world are as follows:
The example of some patent that sold on the world are as follows:
- A plating bath according to claim 8 wherein said composition results from the further inclusion of from 0.3 to 2 weight percent sulfate ions calculated on the chromium trioxide.
