New Vacuum Heat Treat Department in Michigan, USA Now Operational

(Also called; “Why does a manufacturer bring heat treating in house”)

Earlier this year “The Monty Heat Treat News” reported that “Exco” a supplier of dies, molds, components and assemblies for a number of different industries was making very substantial investments in their heat treat departments at several of their facilities around the world. One that we mentioned previously was the firm’s location in Chesterfield, Michigan, USA (details can be found below).

We can now report that this location now has a new, completed heat treat department featuring vacuum furnaces which are replacing the antiquated fluidized bed furnaces the company previously operated at this location.

For more details about the company and their recent financial reports we would suggest this link “Earnings call transcript: Exco Technologies sees Q3 2025 sales dip 4%” . “The Monty Heat Treat News” has reported several times over the years about “Exco”, each of the stories can be found below and they all make for fascinating reading at to why such a large manufacturer would decide to bring heat treating in house.

“April 2025 POSTING; “Exco” is a global designer, developer and manufacturer of dies, molds, components and assemblies for a variety of industries and more importantly to a heat treat news source such as “The Monty Heat Treat News” a company which firmly believes in investing in the latest and greatest heat treat technologies.

Over the years “The Monty” has reported on several of the firms heat treat investments including this news item from 2023, today we mention another heat treat investment the company is making at their facility in Chesterfield, Michigan, USA. The current heat treating department operates fluidized bed furnaces (as a number of the other Exco locations did in the past), however the plant is in the process of phasing out the fluidized bed furnaces and replacing them with vacuum heat treatment. This brings up the obvious question; is there anybody left in North America who still operates fluidized bed furnaces? The project is expected to be completed by the 3rd quarter of 2025.”
