Quality management

One of the main goals of our company policy is prevention rather than eliminating errors. It’s better not to make a mistake than to fix it afterwards. And if a mistake do happens to us, we learn from it so that we will not repeat it in the future. For this we have developed a management tool that is individually tailored to our company and is based on our merchandise management system. This management tool ensures a reliable and sustainable management system. Since our customers approach us with very individual inquiries, they expect the highest quality standards. That is why we want to create trust and we have obtained the ISO 9001 certification.

In order to always ensure the satisfaction of our customers, the employees in our company play an important role.

Every employee in production is continuously encouraged to carry out quality controls independently.
The complete quality control is additionally also carried out by our quality assurance and always documented.

All of our processes are controlled, monitored and documented. Test and measuring equipment is calibrated regularly. Production-accompanying tests and final checks lead to our positive customer reviews. At your request, we create factory certificates according to DIN / ISO.

For specific certifications and standard services not listed on this page, contact our sales team. They will take care to assist you with your demands.
