How to use this calculator :

1. In the first box, enter the thickness that you want your electroform to be plated to. (thousandths of a millimetre).

2. In the second box, enter the surface area of the article in square centimetres (cm2).

3. Click the ‘Calculate’ button.

4. Read off the amp setting for your rectifier and the plating time.

5. If using an amp-hour meter or our Coulometer to monitor the process, read of these figures.

6. If you wish to keep the pH of the copper solution constant, read off how much stabiliser to add.

7. Finally read off the weight of copper that should be plated.
