We attach great importance to ensuring the high quality of our services across all countries. This is evidenced by our DIN EN ISO 9001 certification, which recognised our quality management in Germany back in 1994. Our production sites in Shanghai and Poland also received this certification immediately after their commissioning. By implementing our quality management system, we monitor and document operational processes, which means that they are systematically reviewed. This transparency enables us to continuously review, adapt and improve operational processes in a process-orientated manner.
