Family-owned, Karl Kaldenberg is currently managed by the third generation

Established as sand casting site for yellow metal, Karl Kaldenberg closed during the war and took up operations again in 1945 as sand casting site for copper and light-metal alloys. Since relocating to the current Heiligenhaus site in 1966, the foundry has been extended and modernized continually.
