Quality Management

ISO 9001:2015 and IATF 16949:2016

The term precision is part of our company name and thus expresses a corporate philosophy: giving top priority to the quality of our products and processes. Therefore, 25 years ago we had our quality management system certified according to the internationally valid ISO 9001 standard and subjected ourselves to this globally recognized standard for effective quality management. This means that competencies and responsibilities are regulated and documented in process- and procedural instructions in a reliable and transparent manner, as are structures and workflows. Our headquarters in Erkrath as well as our production sites in Pforzheim (Weidmann), Poland and Tunisia are certified according to ISO 9001. The Erkrath site is also certified according to IATF 16949, the quality management system of the automotive industry.
