Hollow-mould and full-mould casting
Be it hollow-mould casting or full-mould casting, our special steel castings division gives you the reliability you need in the development and implementation of your casting products due to their expertise from melting to processing.
Material selection and a the right casting design are the key criteria for the effective application of a compression mould. Dörrenberg has played a major part in the development of full-mould casting tool elements right from the start and is one of the most important manufacturers of these elements in Germany today.
