Advanced Plating Technologies has named Matthew Lindstedt president, replacing his father, John Lindstedt, who has been named CEO.

Matthew has been with the Milwaukee, Wisconsin, company since 1990. He started in polishing and plating before moving to the maintenance department in 1992. He continued to work at APT during summers and other breaks from Arizona State University. After graduating college and a tour of service in the U.S. Air Force, Lindstedt returned to APT full time in 2003 as the engineering manager. He transitioned into the role of technical sales manager role in 2005, and remained in it until this recent promotion. During his tenure, he is credited with penetrating new markets such as ammunition, firearms and oil/gas, and leading the company to more technically oriented industries.

Tech Talk: Functional Zinc Plating

Electrodeposited zinc is used for coating iron and steel parts when protection from the corrosive effects of the atmosphere is the primary goal. However, zinc by itself, while offering sacrificial corrosion protection based on the fact that it has larger negative electro-potential than iron, is not used without subsequent treatment. Electroplated zinc becomes dull gray after exposure to air, so to get bright zinc, it is given a subsequent post-treatment in a conversion coating that most often contains either hexavalent or trivalent chrome. Non-chrome-bearing conversion coatings have also been employed.

Up until the 1970s, commercial zinc plating had been traditionally done from  a cyanide electrolyte. Because of environmental considerations, other processes were developed.  Today, alkaline non-cyanide (alkaline zincate) and acid chloride baths comprise the bulk of commercial zinc plating. These processes are applicable to both rack and barrel zinc processes.

Typically, in order to bond together two pieces of metal, either both metals must melt a bit where they meet or some molten metal must be introduced between the pieces. A solid bond then forms after metal solidifies again.

Researchers at the Massachusetts Institute of Technology have found that in some situations, however, melting can actually inhibit the metal bonding rather than promote it. This surprising and counterintuitive finding could have serious implications for the design of certain coating processes or for 3D printing, which both require getting materials to stick together and stay that way.

Southwest Metal Finishing of New Berlin, Wisconsin, has a new owner, having been purchased through a court-supervised receivership proceeding by Armor Group Inc., based near Cincinnati, Ohio. Armor also took ownership of Inventix Manufacturing, which Southwest purchased in 2004.

The Milwaukee Journal Sentinel reports, “The companies, along with two other related businesses, filed receivership petitions for the firms in Waukesha County, and their sale is expected to be carried out under a judge's supervision. Both Inventix and Southwest are 90 percent owned by Anthony Fronczak, according to documents filed in Waukesha County Circuit Court. Tony Ristow owns the remaining 10 percent of each firm.”
