Distance in Galvanic/Electroplating bath

Once you have cut a master laquer, you have metal stampers created and have records pressed from them. Discuss manufacturing here. (Record Matrix Electroforming- Plating, Vinyl Record Pressing.)

Distance in Galvanic/Electroplating bath

Hi there!
We at MY45 have set up a brandnew galvanic bath for preplating.
Everything works as it should, but I am not sure, if the distance between
nickel balls (anode) and silvered laquer (cathode) is correct.
I have noticed, that sulfamate is like a resistor, if the silver lacquer (cathode) is more
away from the anode, the resistance is higher, so more voltage is needed to reach the wanted
amperage.
In our 7" rocking bath, the distance is approx. 16cm, in our new rotating bath, the distance is only a few centimeters.
Any suggestions here?
Thank you very much!
Andreas/MY45
