From the raw materials into the factory until the product send out of factory, our quality control has penetrated into every aspect of production. From the temperature control of the electric furnace, to the state analysis of the fiber, to the density of the needling, the flatness after the setting, the size after the forming, and the weight detection. We will be able to meet the requirements of product quality in every aspect, and we know that only in this way can we stand in this industry.
