Electroplating
Dull Zinc Plating
We zinc plate many batches of parts each day. Some of these batches come out dull after the plating and chemical conversion steps. Could this be caused by the base material?
Read MoreDecontamination of Metal Finishing Area
We have a finishing room at one of our plants, and we have outsourced the plating. We also did pickling and bright dip in the room, and we now want to decontaminate it so that we can sell the equipment, or at least dispose of it properly. Our main concerns are cyanide, silver and nickel.

I need some basic information on filtration in the plating shop. My major concern is sulfate copper and Watts nickel.
Read MoreMagnetic Moments
The plating shop says the parts are magnetic when they receive them and the machining operation says they are not magnetic when shipped to the plater.
Read MoreReminder: Blame the Weather
This summer we had a number of days when our plating processes did not seem to work properly. Some days our production would go well with no problems, and other days we were tearing our hair out trying to resolve such things as water spots and other defects. I have been in the plating business for nearly 30 years and suggested that some of the problems have to do with the strange weather we experienced on the East Coast.
Read MoreFailure of Zinc Plating
Our company produces steel components that are welded and sent out to a plating vendor for zinc plating and a trivalent chromium chemical conversion coating. On some of these parts, the zinc plate deteriorates after short periods of storage. Corrosion appears along welds and close to the weld areas.

I would like to know if there are any articles on electropolishing 316L stainless steel, and does your magazine have any bath formulations for doing so?
Read MoreMagnetic Moments Revisited
The plating shop says the parts are magnetic when they receive them and the machining operation says they are not magnetic when shipped to the plater. Do you have any words of wisdom as to how we might be able to resolve this problem?
Read MoreWhen Help is Needed, Call out the Cavalry ... or Calvary Chemicals
Teams of Calvary employees and their families—more than 50 people in October alone—volunteer weeks at a time to provide care for orphans in Monterrey, Mexico through a partnership they have developed through Back2Back Ministries(back2backministries.org). This is not something that company president John Morelock just recently decided to undertake. He has been spearheading the effort since 2004, sponsoring mission trips for employees and their friends and family, providing opportunities to serve alongside Back2Back, and ultimately empowering sustainable long-term change for orphans.
