​It is truly with regret that we mention the closing of one of the oldest commercial heat treating companies in North America, the Robert Wooler Company of Dresher, Pennsylvania, USA. Founded in 1923 the company has a very impressive history which includes NADCAP certification which allowed the firm to service many of the local aerospace companies. At its peak a few years back it had over 40 employees making it a larger than average commercial heat treater. Even recently the company employed 25 individuals and was a viable business, however a number of factors including the difficulty in finding good experienced people lead to the owner deciding to close it down. The last work is being accepted this week and the company will continue to process customers’ parts through at least the first quarter of 2021 with the equipment being auctioned off the second quarter of 2021.

As a footnote to this story we will add that as far as we can tell the oldest commercial heat treater in the USA is Commercial Steel Treating Company in Michigan started in 1916 by Anthony and Ralph Hoensheid.
