We can see that in recent years, the technical content of foreign polycrystalline alumina fiber has been steadily improved, and the polycrystalline alumina fiber has been normalized and applied to high-end components in many fields such as aerospace, civil automotive industry, etc. The domestic high-temperature refractory industry has gradually entered a rapid development period, and the new phase of new material change is coming. As the pioneer of domestic alumina fiber materials, we know that it is impossible to pursue the maximization of our own interests for a long time. Only by adhering to the sustainable development path of harmony and win-win, can we build a lasting business, cooperate closely with customers and partners, build a benign and mutually beneficial relationship in the industrial chain, and realize the sustainable, steady and healthy development of multiple industries.

      With technological innovation as the starting point, we will continue to refine and refine the main business market and always walk side by side with customers. Dongheng's primary responsibility is to ensure the continuous stability of the performance of alumina fiber products, and firmly put the product quality above the company's commercial interests. To this end, we are preparing to build an alumina fiber R&D center, expand the R&D force, complete the R&D and application transformation of a number of core technologies, improve the product series, and enhance the market service and competitiveness; We implemented the technical transformation plan, completed more than ten key equipment upgrading projects throughout the year, and steadily improved the product performance; We set up a quality inspection room for each production, strictly control the quality inspection process, realize the traceability of the whole process data, and ensure the product acceptance rate. We always maintain a high sense of concern, so as to help customers avoid product use risks and continue to win the trust of all stakeholders.

        Adhere to the coordinated and balanced development of the upstream and downstream of the industrial chain, and always walk side by side with partners. Creating a harmonious and stable business environment is the basis for business connectivity and cooperation. We adhere to the development concept of "joint development of enterprises and employees", and raise the number of professional talents by quota every year. The proportion of highly educated and highly skilled talents has increased by 15%, and the proportion of skilled talents has increased by 45%. Many young technical backbones have taken more important positions, and highly skilled talents have become the backbone of the company; We integrate the sustainable development strategy into the supply chain management system, promote the end-to-end supply cooperation model, and provide higher value returns for suppliers; We pay attention to the development strategy of industrial park clusters, maintain the mutually beneficial and symbiotic partnership, adhere to the development model of ecological clusters, give full play to the value advantages of the composite industrial chain, and make greater contributions to the regional economic development.

         There is no end to the road of sustainable development, let alone overnight. We will continue to improve the company's business planning system, reasonably develop and utilize chain resources, promote the efficient implementation of various objectives, and achieve the organic integration of resource utilization and enterprise development. We will also make greater contributions to the harmonious and healthy development of the industrial chain through continuous efforts and practice. The way is long and the way is coming. We are full of confidence in the future development.
