MEDIUM TRIPLE CHROME PLATING LINE

Pictured here is another example of a triple chrome plating line.  This line was set up for doing zinc die cast and pot metal restoration.  The line includes the Electroscrub, Alumkleen, Activator, Alkaline Copper, Bright Copper, Bright Nickel, and Kleen Chrome (old school chrome) as well as TC Chrome (trivalent chrome).

The Electroscrub is used to clean steel, brass, lead, pewter, and copper parts.  Alumkleen is used to soak and clean buffing compound off aluminum and pot metal.  Metal Activator tank prepares various metals for electroplating by micro etching and activating the base metal to be plated.

Pictured above is the Alkaline Copper tank.  This solution is used for strike plating any metal to insure greater adhesion of the proceeding plating processes.  This solution is very stable and very easy to use.  It requires very little maintenance.

Bright Copper is a high efficiency copper plating solution that plates faster than almost any other plating solutions and is used to build up a thick coat of copper.  This thick copper plate is used to fill in machine lines, pits, and other minor imperfections in the base metal.  This coat of copper can also be buffed to a high shine.

Bright nickel tank is pictured here from two separate angles.  Bright nickel plates a bright, shiny, chrome like finish on a part that resembles chrome plating.  To the right is the nickel rectifier and the chrome rectifier.  The smaller white rectifier is used on nickel because it does not require much amperage to plate.  The blue rectifier puts more amperage because both forms of chrome requires more plating amperage to plate properly.  TC Chrome requires about 4 times more than nickel and Kleen Chrome requires 7-8 times more than nickel, which is double the needs of TC Chrome.

Above are the two chrome tanks.  The one on the left is the TC Chrome, which is trivalent base chrome.  It is easy to used and very lightly regulated by the EPA.  The tank on the right is the Kleen Chrome tank.  This is what many refer to as 'chrome'.    They both are chrome and each of them has advantages and disadvantages.  Not sure which one to use, why not set up both as is the case with many commercial shops.  You get the best of both worlds.

Evaporator waste water system for plating shop waste  Waste water system for anodizing shop waste

The final group of pictures are photos of the waste treatment center.  Because this shop has only a 200 gallon triple chrome line and a 60 gallon decorative color anodizing line, there is not a large rinse water disposal need.  The one hundred fifty or so gallon of rinse water produced each day by this shop is easily removed by this evaporator system.  The rinse water is pumped into a storage tank and then sent to the evaporator and each hour about 20 gallons of water is evaporated off by this device.
