Quality assurance

Item 1 of 6

We supply the beverage industry around the world with our "Made in Germany" glasses. Our quality management has installed a comprehensive quality assurance process. In this way, we ensure that our national and international customers are supplied with glasses of consistent Ritzenhoff quality. We check our glasses digitally and manually from the very beginning and throughout the entire production and finishing process. Thus, even the first blanks are sorted in a manual selection while still on the machine. Only the goblets that stand up to the scrutinizing gaze are given stems and feet in the second work step. The batches are checked continuously and in random samples and compared with predefined limit values, the data is stored and production is fine-tuned accordingly. In this way, the natural quality fluctuations of the difficult material glass can be controlled and kept within predefined tolerances.
