Quality Control

At Win Win Cookware, quality is at the heart of everything we do. Our tempered glass lids undergo a rigorous 6-stage inspection process, including thermal shock testing (up to 250°C), temperature differential tests, fragment tests, and drop tests from 1.5-meter height. Each stainless steel handle and knob is tested for 50,000+ rotations and high-temperature resistance to ensure durability under extreme conditions. We implement AQL 2.5 standards, with every batch subjected to random sampling and detailed documentation. Our dedicated QC team uses advanced tools like laser measurement and salt spray testing to guarantee precision and longevity. From raw materials to finished products, we ensure every component meets FDA, LFGB, and RoHS standards, delivering reliability you can trust.
