Eight decades of providing our customers with innovative products and services have made Kautex into one of the world's leading companies in extrusion blow molding technology.
We have built our success on the courage, curiosity and passion for technology shown by founder Reinold Hagen and his brothers. During more than 20 years as a subsidiary of the Krupp group, we grew to become one of the world's leading mechanical engineering companies. Today, our global patents are steadily accumulating, helping us to make a major contribution to the development of extrusion blow molding technology.

The combination of private ownership and a majority shareholding by Kautex management ensures that the company continues to maintain the dynamic character of a medium-sized enterprise with a high level of customer orientation. Every member of our staff is involved more than ever before in forging our company’s success. Individual knowledge and experience, the ability to work as a team and an unshakeable belief in their ability to find technical solutions are the foundations of our success today.

Our position as market leaders and our ability to develop innovative products and services is the direct result of our commitment to focusing on the specific needs of our customers. These needs drive us to continue optimizing our internal processes and procedures and trigger the development of new and better products and services. Our customers are our biggest source of inspiration. Every day, their challenges become our challenges and we work together for our mutual success.
