Our targets

We have set ourselves ambitious targets. First and foremost, we want to optimise our costs every year. This is not to be achieved by low prices alone, but by reducing our quality-, logistics- and process- costs. We are therefore constantly striving to optimise value creation along the supply chain.

How can we make our products more cost-effective through optimised technical parts and assemblies and thus offer innovations added value for our customers?

How can we simplify / digitalise our procurement processes with you?

We strive to achieve these targets with our suppliers in a long-term and fair partnership

Our expectations

We require the highest demands on the reliability and performance of our existing and future suppliers.

Therefore, we need suppliers who meet our requirements both economically and technically and who are willing to continuously develop together with us. An essential point in the cooperation is a high degree of flexibility, quality and adherence to delivery dates.

Ideally, selected suppliers are already involved in the process during the enquiry development phase of new products in order to jointly develop cost-optimised solutions for the customers.

Our Transport and packaging instructions for suppliers and codes of conduct must be adhered to.

If it is foreseeable that the required delivery date cannot be comply, it is mandatory to inform us immediately. The reasons leading to a delay in delivery must be investigated. In case of emergency, all possibilities must be taken to reduce the delivery time.
