During the 40 years of development and construction. We have always adhered to the development orientation of prioritizing talents and strengthening enterprises and enriching employees through science and technology. We have successively established the China High-Efficiency Heat Exchange Finned Tube Professional Committee, and set up research institutions such as the Provincial Engineering Technology Research Center, the Provincial Enterprise Academician Workstation, and the provincial Enterprise Technology Center. We carry out industry-university-research cooperation with institutions such as the Shenyang Institute of Metal Research, Chinese Academy of Sciences and Shanghai University of Science and Technology, and invest no less than 3% of our annual sales revenue in the research and development of new products. Cuilong Technology has obtained 38 utility model and invention patents with independent intellectual property rights, including 2 US patents and 15 invention patents. This has formed the international quality of core technologies of Cuilong Technology. The performance of all products has reached the international advanced level, breaking the foreign technological monopoly. The product won the First prize of Science and Technology of China Nonferrous Metals Industry. During the 40 years of market development. Closely following both domestic and international markets, the provincial brand high-tech products are sold in over 10 prefecture-level cities across the country and more than 10 countries and regions. The annual sales volume accounts for over 30% of the domestic market share of similar products, leading domestic peers. Our company is highly favored by both domestic and international users. Among the world's top five refrigeration and air conditioning enterprises, four manufacturers in China are our main customers. For more than ten consecutive years, we have been rated as an outstanding supplier by wholly foreign-owned enterprises such as Johnson Controls York, McQuay, and Dunham-Bush, which are among the world's top 500 companies. In the 40 years of technological progress. The company has been committed to the development and construction of production, product fields and talent cultivation. The first is to focus on upgrading within the industry and shift towards the production of high-value technology-intensive products. In 2013, another 150 million yuan was invested to build a new high-precision horizontal casting and rolling production line with a capacity of 15,000 tons. 30 CNC fin forming machines were imported from the United States, and the first dual-station performance test bench for domestic fin tube manufacturing enterprises was added. The equipment installation has reached the international advanced level. Second, expand the product range. The company has been engaged in the research and development of high-finned tubes since 2005. Currently, it has established a specialized high-finned tube production workshop and developed a series of high-finned tubes with grades such as C12200 and C70600, including 1-inch 5-tooth, 1-inch 7-tooth, 1-inch 9-tooth, and folded fin types. These products are used in heating systems such as boilers and the HVAC industry. A.o. Smith, an expert in the water heater industry, has made a designated purchase of this series of products from our company, which has become a new highlight in the development of the enterprise. Thirdly, it has spared no effort in cultivating and attracting talents as well as intellectual development. It has successively cultivated over 31% of the total number of personnel with college degrees or above and various types of technical personnel, and the research and development of new products has been continuously improved. The product development has been updated to the sixth generation of high-efficiency, energy-saving, environmentally friendly, green and high-end premium products, and a series of high-performance and low-voltage drop products have been developed. After 40 years of strategic development, it has the ability to develop high-end markets, research and develop high-tech products, transform scientific and technological achievements, and manage intensively and scientifically. Moreover, it has the potential to continuously surpass and develop. We will continue to grasp the new normal of economic development. The development of scientific and technological innovation is always on the way, and Cuilong has great potential. The company has been in operation for nearly four decades, accumulating strength and achieving remarkable results. Looking to the future, the company's development strategy is positioned as follows: First, firmly grasp the upgrading within the industry and expand the product range; The second is to develop a new generation of technology-intensive, environmentally friendly and high-performance heat exchange tube products. The third is to expand in the direction of globalizing the supply of high-end markets.
