We produce a wide range of strip springs and stampings for the automotive, textile and consumer goods industry, and we offer a variety of heat treatment processes. As a member of the KERN-LIEBERS Group, we take profit from the joint expertise of our group of companies to always provide the best problem solutions and process excellence to our customers.


KERN-LIEBERS CR was found in České Budějovice in South Bohemia in 1994. Our first products were manufacturing of springs and spring assemblies for seat belts.

Since 1999 we also produce stamped and fine blanked parts for the automotive industry.

In 2002, we built a new production hall so that we can also offer various methods of heat treatment on contract basis since then.
