“Gord Montgomery” of “The Monty Heat Treat News” had the opportunity just yesterday, March 18th, 2025 to see a really impressive captive/commercial heat treating facility in Dravogradu, Slovenia.

 

Let’s start at the beginning of our story;

 

Family owned “Miheu d.o.o.” located in the town of Dravogradu, Slovenia was founded in 1974 as small, humble commercial heat treater featuring “pit carburizing” furnaces. A big step in the evolution of the company occurred in 2008 when the firm acquired an automated carburizing line from Switzerland based “Codere”, a line which is still in service-since that time the company has added many more furnaces and has never looked back.

 

Over the years the firm has expanded from commercial heat treating only into one which offers heat treating and also manufacturers high precision shredder blades and distance rings used in industrial shredders for recycling of various materials-hence the fact that Miheu is both a captive and commercial heat treater.

 

As of this printing the company’s revenue is 50% commercial heat treating and 50% new machined products which translates into roughly 8 million Euro in total sales for 2025-mumber of employees is now 45.

 

As our focus is on the heat-treating side of the business, we will mention that over the past 10 years Miheu has invested over 10 million euros (roughly the same in USD) in the heat treat department and it shows, meaning it is a very clean, modern heat treat facility.

 

Heat treating is housed in its own brand new (since 2022), 2,000 square meter facility located just a few kilometers from the main office. Current business conditions mean that it is processing over 4,000 tons of steel per year.

 

Except for Induction hardening and salt quenching there are virtually no heat treating processes which the company does not offer, LPC (Low Pressure Carburizing), Carburizing, Gas Nitriding, Plasma Nitriding, Nitrocarburizing-the company offers every single one of these heat treat processes.

 

Our visit was hosted by “Mr. Ales Prikerznik”, Director of the company and joining us was “Mr. Harald Roth” of German furnace builder “KGO” . KGO provided a pit nitriding furnace to the company which entered production in 2021-Harald, Ales and the furnace can be seen in two of the pictures below.

 

“Miheu d.o.o.” has featured prominently in several press releases issued by furnace builder “SECO/WARWICK” over the years and we can see why, “Miheu” has a number of quite new furnaces from the company including a “LPC” (low pressure carburizing) system which entered production in 2022-this is in addition to several “SECO” vacuum hardening systems which can be seen in at least two of these photos.

 

We thank “Mr. Ales Prikerznik” of “Miheu”, besides the fact that he is a very knowledgeable heat treater he is also a tremendous host. “Gord Montgomery”, “The Monty Heat Treat News”
