I am handling a hard chrome plant, and there we do chrome plating on cylinders, rollers etc up to a length of 3.10 metre and diameter 28 inches.
So to save on things, what should be the ideal temperature at which the process should go on and what can be the other methods that we can put in to have better efficiency without compromising of quality.
And is there any way to save on those big electricity bills?

Hi, Rishi. As you may know, there are whole books written just on hard chrome plating. Guffie's "Hard Chrome Plating" is one, Clarence Peger's "Chrome Plating Simplified" is another. So, when you ask the ideal temperature, the answer would depend on such things as whether you are using the more conventional approaches discussed in Guffie (maybe 140 F) or the reversible-rack system advocated by Peger (as much as 160 F).

Conventional chrome plating is only about 12 percent efficient, so one way to save electricity might be to try Atotech's HEEF-25, which is claimed to be 25 percent efficient (other suppliers also offer this proprietary approach), or to try Peger's idea of higher temperature and higher current density. Good luck.
