8 Micron gold plating on silver or brass

Sir,

In India silver jewellery is very popular however it can not replace
Gold so there is a very big requirement for high quality gold plating
which is not done all around and the technology is not available
freely, please can you discuss the technology and equipment needed
for this guaranteed gold plating??

It will be appropriate to also suggest the cost of machinery
involved if some thing special?

Thanks
