  • A-Class defines 'functional' coatings as those that serve another purpose than to make an item look good though this is an important function of some coatings.

For example electrical fittings tend to perform better (in the conduction of electricity) when assisted by a tin or silver coating (depending on the application).
Parts are processed by either rack or barrel.

Rack plating for larger items and barrel plating for large quantities of small parts. Some of the functional metal finishing processes performed at A-Class are:

TIN PLATING

Tin plating is primarily used in the electrical industry for the purposes of:

  • Electrical connections
  • Corrosion prevention
  • Solderability

A Class has the facilities to rack plate to 2 metres in length or barrel plate small items.

SILVER PLATING

Silver plating (functional, not decorativve) is primarily used in the electrical and electronic industry for the purposes of:

  • Electrical conductivity
  • Electrical connectors

A Class has the facilities to rack plate larger parts up to 2 metres in length or barrel plate large volumes of small items.

HIGH PURITY SILVER PLATING

The high purity silver process is used primarily in the electronics industry for radio frequency applications where the maximum conductivity of the silver can be utilised due to the extreme electrical conditions the components will be exposed to.

HIGH PURITY GOLD PLATING

High purity gold is used in situations where high conductivity is required but where corrosion resistance is also a major concern and is used for many electrical or electronic applications such as plugs and connectors of all sorts. Another application is for laser reflectors.
