    – new sites in Kassel and Baunatal



Experienced in the heat treatment of steel and aluminium components and the mechanical processing of unmachined parts into ready-to-install, finished parts

The Hanomag Lohnhärterei Group has been one of Germany's leading hardening plants for over 30 years.

We offer a complete range of heat treatment processes and our services extend to numerous upstream and downstream processes, measuring and testing.

Our ten sites are equipped with the latest plant technology and our experienced specialists mean we can offer you component-specific, sophisticated heat treatment concepts. We think just-in-time logistics and transparent communication about the entire treatment process are standard business practice.

A lot of customers want a responsible supplier, from unmachined parts to tested, ready-to-install finished parts, so we have also installed mechanical machining centres at many of our sites to complete the process chain.

We can advise you about materials, help you to identify the best possible heat treatment for your requirements, and the most cost-effective manufacturing process for your components.

Welcome to the Hanomag Lohnhärterei Group!
