Do Manufacturers Make Good Commercial Heat Treaters-Kern Liebers
Over the years “The Monty Heat Treat News” has had the privilege of visiting two locations of Captive/Commercial heat treater Kern Liebers Schramberg, Germany and Queretaro, Mexico-visits which resulted in an article in 2018 entitled “Do Manufacturers Make Good Commercial Heat Treaters”. The original article is further down in its entirety but to quickly sum up Kern Liebers is a German manufacturer who heat treat their own products in house but who also offers commercial heat treating at 6 of their global locations, a combination which is reasonably rare and even rarer is the fact that they seem to make money from it.
In addition to the notes below “The Monty Heat Treat News” has also mentioned the company when they installed a new vacuum nitriding system from German furnace builder Rohde, a picture of which can be found here.
The company makes our news section today for the fact that they continue to flourish and a result is this brand new addition to the Queretaro, Mexico plant. What you see here is an IVA Schmetz, high pressure nitrogen quenching furnace with working dimensions of 36” X 36” X 72” which just arrived last week. This furnace will join 2 vacuum nitriders, a large pit furnace and several other styles of furnaces all dedicated to both captive and commercial heat treating.
“MAY 13/2019 QUERETARO, MEXICO; Kern Liebers is a company which intrigues us as they seem to be that very rare of breeds, a company which successfully combines manufacturing with captive and commercial heat treating. Recently they have been promoting themselves with press releases such as this combined with a photo of the plant in Mexico. “We present the two plants KERN-LIEBERS MEXICO in the state of Queretaro. One of them is dedicated to the production of stampings, stampings and heat treatments, while the other is focused on springs. More than 540 employees work in these facilities of 22.400 square meters of extension, where we offer amenities such as a gym for the exclusive use of employees and their families, among others.” To go with this news item we include our original news item from a few months ago along with a photo of part of their heat treating department.
“OCTOBER 2018 PRESS RELEASE; Do Manufacturers Make Good Commercial Heat Treaters? Kern Liebers; Generally our opinion is that manufacturers who have in house heat treating capacity make poor commercial heat treaters for a wide variety of reasons. However having said that we very recently visited a manufacturer who for years now has been offering commercial heat treating from their in house heat treating departments and has been very successful at it. KERN-LIEBERS is a medium-sized family owned company based in southwest Germany who specializes in the production of highly complex strip and wire parts and assemblies. The KERN-LIEBERS group of companies develops and manufactures precision products at over 50 locations around the world and currently 6 of these locations have in house heat treating capacity which offer commercial heat treating.
Two weeks ago we visited the Schramberg, Germany location which has the ability to offer Gas Nitriding, Nitrocarburizing – also of stainless steels, case hardening, carburizing, austempering and vacuum hardening. One look at the equipment tells us why the company is successful at commercial heat treating, it is new and varied In addition as Kern Liebers services a number of different industries they have a wide variety of certifications including IATF 16949 and CQI9 to name a few. While a majority of the heat treat capacity is dedicated to their own products by sales volume, the commercial heat treating side of the business is substantial and contributes a significant part on it. It is important to note that while the company probably did not set out to be a commercial heat treater they certainly treat it as an independent profit center with worldwide heat treatment .
Mrs. Li Haas firstname.lastname@example.org is working for the sales department in Germany, who is connected to all the heat treatment teams of the other locations. Other locations offering commercial heat treating include China – Taicang near Shanghai and Tianjin near Beijing, India – Tumkur near Bangalore, Czech Republic – Budweis, and Mexico – Querétaro . While many of the processes are duplicated in the various locations some such as Plasma Nitriding is only available in one location (Taicang/Tianjin, China) or Induction Hardening which is only available in India and the Czech Republic. As we speak the company is making major investments in many of their plants, including two new pit furnaces from Rohde Furnaces in Germany-one for the Mexico location and another for the Czech Republic. Rohde is also in the process of installing 2 new vacuum nitriding furnaces in Mexico. Rohde has already equipped all worldwide Kern Liebers plants with either pit or chamber furnaces. Other planned additions include more of an emphasis on nitriding capacity especially in China and especially as it relates to heat treating of stainless steels. So while we feel that most captive heat treaters do not make a good commercial heat treater we can point to Kern Liebers and say; “here is a company that manufactures a very good product and is also a darn good commercial heat treater.”
