Yongrui utilizes state-of-the-art Japanese high-definition, high-sensitivity infrared intelligent inspection equipment, supported by a 24/7 self-inspection and audit quality management system. This comprehensive approach contributes significantly to consistent product quality and safety.
A dedicated QC team oversees high-quality online inspection systems, including leak tests, adhesion tests, contamination checks, and pre-warehousing final inspections. Collectively, these measures work to ensure good product quality before shipment to customers.
Additionally, our in-house product testing laboratory conducts various tests such as top diameter, bottom diameter, height, stacking strength, curl, stiffness, and grammage. This capability supports effective control throughout the entire production process.
