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 for the long term. In doing so, we can always rely on the support of the KOSTAL Group, backed up by its expertise and decades of experience.

Errors are there to be eliminated

We all know that, for the most part, the problems lie in the details. That's why we do everything we can to avoid them 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 are happy to take on board suggestions from our customers and learn from the experience of others to achieve these goals.

Quality products

KOSTAL uses only components from suppliers certified in line with 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.
  • It is the company's stated goal to obtain international quality certificates and quality awards in an effort to prove KOSTAL to be internationally competitive.
  • We formulate custom solutions in individual dialogue with our customers, where high-quality communication is absolutely key. This means that we only present our customised proposals after detailed discussions on site and a targeted analysis phase. We also ensure that each customer has a contact who can answer their questions clearly and professionally.
