What are the steps in chrome rim manufacturing?

+++

I am doing a project on chrome rims, I was wanting to know the process that the manufacturers have to go through to make them. All the layers, what types of metals are used etc.

Thank you,

Older cars, and less expensive cars, usually have stamped steel rims. Newer and fancier cars usually have pressure cast aluminum wheels with fancy spoke shapes. Either can be chrome plated.

There are variations in the plating process, but one sequence for aluminum wheels could be: clean the rim in hot inhibited caustic, rinse, desmut in nitric acid, rinse, zincate, strip in nitric acid, rinse, re-zincate, rinse, electroless nickel plate, rinse, acid copper plate, rinse, buff, caustic clean, rinse, activate in sulfuric acid, rinse, semi-bright nickel plate, bright nickel plate, rinse, chromium plate, rinse, dry.
