BK Stanz- und Umformtechnik


Berthold Kunrath established the family owned business over 50 years ago. In an environment influenced by innovation and technological change and with high quality standards, we are happy to say that we found our place as a forward-looking, highly productive sheet metal forming manufacturer. We are based in Theley in the north of the federal state Saarland, Germany where we employ 80 – 100 workers.

We work with clients from all different types of industries. Our main focus lies currently on the automotive industry, it’s component supplier sector as well as on building and engineering industries.
Reliability, outstanding customer support and the willingness to try something new are just a few terms that describe our company and show what makes us a valued partner for clients from all over the world.

In recent years, we made several investments to extend and modernize our machinery. A 3-axis and 5-axis milling centre and a new 3D laser machine have been purchased for our tool making department. The biggest single investment has been made for our sheet metal forming department. A new 630 t deep-drawing press and an electronic transfer device with 3 axes.
