Metal Finishing/Plating

What Is The Process?

The metal finishing/plating process and why cooling is required.

  • An electric current is run through a solution, the metal to be deposited is used as the anode and the work piece is used as the cathode the negative ions flow from the anode and are deposited on the cathode to form a protective finish

Why Is Cooling Required?

Tank Cooling - The electrical current that is required to create the reaction heats the acid bath which then needs to be cooled to the correct temperature.

What Must The Cooling System Include?

The chiller cannot circulate around the tank; there are two ways of cooling either using a coil in the tank or heat exchanger. Either way the materials must be suitable for the tank solution. The chiller system including the heat exchanger needs to supply the solution back into the tank lower than the required temperature (see tank cooling). Do not site the chiller in the same area as the tanks as the atmosphere will eat the condenser, in some plating plants the chillers are on the roof and the ventilation extracts from the factory are in the same area, if this is the case coat the condenser.

Call Our Experienced Engineers

Aqua have many years experience in the Metals Industry. Should you require metal finishing/plating system cooling please give our experienced engineers a call. Before speaking to us, please try and answer the following questions as thoroughly as possible as the more information you can provide, the easier it will be for us to help:

  • What is the temperature of the chilled water required?
  • What is the temperature of the returned chilled water?
  • What is the flow rate required?
  • What is the maximum AMPs used?
  • What is the maximum Volts used?
  • What is the fluid used in the system?
  • Do you need antifreeze protection?
  • Is the heat exchanger or coil method used?

We look forward to speaking to you soon and helping you with your metal finishing/plating cooling system requirements!
