“The Monty Heat Treat News” just posted a heat treat industry exclusive in the form of a list of the “The 52 Largest Commercial Heat Treaters in North America” based upon estimated sales for 2025. Amongst those on our list was “Vac Aero International”-the largest commercial heat treater in Canada and also a major vacuum furnace supplier. We are now hearing a very interesting rumor about the company-specifically that they are putting the “International” back into the name of “Vac Aero International” in that they will be putting a “shop in a shop” somewhere in the southern USA. 

“Shop in a Shop” refers to the practice of taking over the “in-house” heat treating department of a manufacturing facility who wants to keep heat treating in house while not having the responsibility of the day-to-day operations. If this rumor is true, it would be one of the first major investments by “Vac Aero” into the US market in the form of a heat treat facility (we will add that the company has many vacuum furnace installations in the US and around the world). 

Updates to this “rumor” will be available on this site as we learn of them.
