Smart Manufacturing
Modularized fully automated production lines enable fast delivery and cost savings. To achieve a high utilization rate and efficiency, the whole production chain is divided into separate but closely united automated production sectors. Over 40 patents are applied to production process optimization, which effectively avoids manual errors and ensures all production processes from raw material inspection to packing are monitored online and saved for later use. This system ensures that materials from the beginning of production to packaging are completely monitored online.
Quality Control
Stringent quality control is the cornerstone of our manufacturing. Our customers have come to expect uncompromising quality standards in our products. To meet this expectation of high quality, we continue to invest in state-of-the-art equipment and professional training of our employees. We are proud of our product quality and their reliable performance even in the most extreme conditions.
The manufacturing facilities have received certifications for Quality Management System (ISO 9001:2015), Environment Management System (ISO 14001:2015), and Occupational Health and Safety Management System (ISO 45001:2018) from both DNV GL and GZCC.
