Our management systems

Quality, efficiency, environmental protection

We take responsibility

As a private open-die forge, we not only want to impress with first-class products – we also face up to the challenges of an increasingly complex and sensitive environment.

In addition to the highest quality standards, environmental protection and energy efficiency are therefore an integral part of our corporate policy and an important task of company management.

We realize economic goals and ensure that we treat our environment with care. For this reason, all our production processes are checked for their environmental compatibility and energy efficiency in addition to economic and technical requirements.

We have adopted the following environmental and energy policy in recognition of these interrelationships and our shared responsibility for environmental protection. It is binding for all employees and applies to all activities at Karl Diederichs GmbH & Co KG.
