Our QC Department has established a complete network to manage production and quality. There are four steps for quality control: factory, workshop, working shifts and individual worker. The department is well equipped and has very strict control over quality inspection from the selection of raw materials (PET) until the final products. A perfect and pragmatic management system as well as systematic training and education make all workers aim towards the goal of "No Inferior Quality" and allow the factory to guarantee the quality of its products.
