Hard chrome plating books

--

Please tell me more about hard chrome plating, for example the ideal current density, voltage, temperature, solution percentages, etc.

I'm starting a hard chrome plant for rollers and plastic molds.

Thanks for any suggestions.

-- Hi, Remberto. There is a very lot to it (four different general types of plating baths based on their catalysts; tank plating vs. reversible rack plating; etc.) so you're probably asking for a book or two, rather than a paragraph or two. You can try Chromium Plating by R. Weiner, or Guffie's excellent book, => The Handbook of Hard Chromium Plating. As an alternative you might get hold of old issues of Metal Finishing magazine and read what Clarence Peger has to say. Best of luck. Ted Mooney, P.E. finishing.com Brick, New Jersey

Hard Chromium Plating

In addition to looking at past issues of Metal Finishing magazine for Clarence Peger's articles about chrome plating, get a copy of Clarence Peger's books about chrome plating.

Hard Chrome Plating Simplified (CPSR) - a manual that consists of basic, simplified, hard chrome plating information to help you make greater profits; with over 200 illustrations and photographs; also includes 32 blue prints. 382 pages. $150.00

Hard Chrome Fixtures II (BLFT) a manual consisting of 80 full-color photographs of chrome shops, racked work, and other related images, 15 black-and-white photographs, 8 line-drawings, 5 papers, back issues of Hard Chrome Plating news letters, and other informative articles. Each photo has a commentary. 300 pages. $175.00.

All of the information in these two manuals is based on a proven high-speed chrome plating method that produces even deposits at 0.006 + per hour plating rates. These manuals have been called the Hard Chrome Plater's Bible and the Cook Book of Chrome. If you plate, you must have these manuals!

These manuals are available from:

Hi guys, Can anybody give me some hints of the operation costs of running a chrome plant?

Hi, Rolando.

As with many businesses, labor cost is probably the biggest single item. It can take several hours (or even more) in the plating tank, and the plating job often requires careful masking, building of specialized auxiliary anodes and thieves, etc.

Electricity costs can be substantial: look into Faraday's Law to estimate electrical usage based on the amount of chrome you will deposit, remembering that the chrome is in hexavalent form, and deposition efficiency is probably only about 12 percent. The air exhaust system also uses substantial energy.

The chromic acid itself is a fairly minor cost, but it can be expensive to manage the handling of chromic acid (hexavalent chromium) to avoid worker exposure and pollution of the environment. Good luck.
