The polished parts, having been masked if necessary as mentioned in the
previous section are wired up on jigs. They are now immersed in an electrolytic
cleaning bath, a current is passed through them reversing the polarity,
thus drawing any remaining residue from its surface, then rinsed in clean
water. Steel parts would then be rinsed in a 10% sulphuric acid bath.
Aluminium parts are treated chemically for about 30 seconds to etch the
surface, then rinsed again. Before going through a sealing process for
1 minute to seal the pores of the aluminium.
All parts are then coppered, lightly or heavily depending on their usage,
(internal or external). Brass parts are not normally coppered. After the
coppering process most parts would normally be 'copper finished', (polished
again on the copper) rewired to a jig and after going through the cleaning
process again would be 'nickelled'. We plate very heavily for obvious
protection advantages because contrary to popular belief it's the nickel
not the chrome that gives you all the protection against the elements.
the nickel process, all parts are then polished yet again and then rewired
prior to going into the chrome vat to put the final lustrous coating on.
After the chroming process is complete, all parts would then be unwired,
polished with a duster, inspected and wrapped prior to collection.
As you can see, to do properly it is not a quick dip, but a highly
specialised process, and there are no short cuts if you want to achieve
the desired result.
All of our work is guaranteed and is of the highest standard.
