Cycle Times for Anodizing, Bright Chroming and Electropolishing




2006

Hello, I work as a cost estimator (I would consider myself a "rookie" when it comes to finishing processes, etc.) and am trying to learn about the cycle times with respect to the following: 1) anodizing Aluminum; 2) Chroming Steel; 3) Chroming Aluminum and 4) Electropolishing.

There are some articles, etc. that show the various processes and some of the preparation work (i.e. wheelabrating, etc.) that oftentimes is necessary to get a "good finish", but as of yet, I haven't had any luck finding any information on actual cycle times.

Put simply, how long would it take to process 1 part through each of the aforementioned processes? For instance (10 minutes in this tank, 15 minutes in this tank for a 4 hour total time ). I understand that there will be many parts on a rack, etc. but I am trying to gauge the relative time so I can differentiate between the processes for potential cost savings potential.

If there are books/literature that I can reference, that would be great as well. Better yet, if there are models for painting/finishing that exist, I would consider this to be the proverbial "Holy Grail" for estimating.

Any information/advice that you could provide would be very beneficial to me personally and professionally -- thank you.

Hi. I'm a Brazilian enthusiastic amateur about metal plating, and I'm facing some troubles to determine the actual cost of metal finishings, esp. for rotatory zinc plating. Does anyone have a spreadsheet that could be used to determine the cost of the process? Don't matter the currency of the spreadsheet, I can adjust it to our own currency. All I need is some help about the procedures to account raw materials (esp.), energy and labour costs (desired, but not essential) related to metal plating. Thanks.

You need a copy of the Electroplating Engineering Handbook [on AbeBooks or eBay or Amazon] .
You might use the link from this site for Amazon and get a used one. Another good reference would be the plating and the painting books that come with a subscription to Metal Finishing. There is a link from this site. Beg for a copy of each when you start. They are normally sent after the new ones are printed.
