Process method, system method and fact-based decision-making method are adopted. After obtaining the ISO9001 quality management system certification, the company has been in accordance with the quality management system GB/T19001-2008 edition standards and the company's "Quality Manual" and related procedures for the company's internal quality of a comprehensive management. Continuous improvement as one of the essence of modern quality activities, has reached the basic quality requirements on the basis of further improvement, is an endless process, the company will continue to improve as an eternal goal.

Enterprise standards and inspection standards for various products
As the first large-scale polyimide fiber manufacturer in China, the company has successively formulated the first domestic enterprise standards of "polyimide resin", "polyimide short fiber" and "polyimide filament" according to the requirements of the market and the actual production of products. Enterprise product standards are not only the basis for measuring and evaluating product quality, but also the basis for organizing production in practice, which accurately reflects the needs of consumers and lays the foundation for the next step to establish industry standards and even national standards for polyimide fibers.
The company has developed a product testing process and inspection standards, from the raw materials of the product to the production process to the final product, are strictly monitored to ensure that the company's products to meet customer requirements on the basis of improving customer satisfaction.
