Quality at all levels

In our modern production building in Hagen, we develop new solutions for the energy of the future, which will also keep our customers satisfied in the long term. In doing so, we can always rely on the support of the KOSTAL Group, which stands behind us with its competence and its decades of experience.

Errors are there to be eliminated

We all know that the devil is in the detail. That's why we do everything we can to avoid errors right from the start. We use the zero-error approach, which is applied throughout all the business divisions of our company and places the focus on the quality of our work, our products and our services.

Striving for quality

Potential sources of error are analysed and intercepted back at the time of product development. We do this through the use of preventive quality tools, which we have developed for this purpose. However, after reaching series production, we still continuously monitor the quality of our products and constantly work to figure out possible improvements. We're happy to take on board suggestions from our customers and learn from the experience of others to achieve these goals.

Quality products

KOSTAL only uses components from suppliers that are certified according to our high quality standards. 

  • In order to achieve our quality goals, all employees participate in ongoing training aimed at enhancing their customer focus and quality focus.
  • Our managers are role models for their employees. They must formulate clear, achievable goals and assist their employees in realising them. They are responsible for making sure these goals are met.
  • Obtaining international quality certificates and quality awards is the declared goal of the company in the effort to prove the international competitive abilities of KOSTAL.
  • We generate customer-specific solutions in direct dialogue with our customers. In the process, the quality of the communication with our customers is of particular importance. That means that we only present our customised proposals after detailed analysis and project-related discussions with our clients. We also ensure that each customer has a contact who can answer their questions clearly and professionally.
