THE MODERN
HEAT TREATMENT CENTRE

Our company was founded in 1928 as a metal saw factory. The necessary heat treatment was conducted in the factory itself. After orders from Remscheid companies had started to increase greatly, the management decided to expand the production branch of hardening technology. In this way, one of the most modern heat treatment centres in Europe came into being.
