From the start of production until today, we have promoted the establishment and operation of high-quality facilities and production processes. Our manufacturing facilities are certified according to ISO 9001,and ISO 14001. The quality control systems are effectively, comprehensively and strictly enforced at every single production level - from material supply to the shipment of the finalized products. As a vertically integrated company, we direct influence on the product quality along the entire value chain.
To ensure product quality from the beginning on, external suppliers and their products are subject to a strict quality assurance process, including laboratory testing to ensure product compatibility and reliability and on-site assessment. Following this, continuous feedback and corrections ensure the quality and stability of our raw material supply.
