Since its establishment, the company has been committed to the development and production of high-precision copper tubes for air conditioning and refrigeration with innovation, development, focus on quality, and the pursuit of excellence. After more than 20 years of development, the company has established a leading position in the precision copper tube industry. The company owns the National Enterprise Technology Center, the Precision Copper Tube Engineering Research Center of the Chinese Academy of Sciences, a postdoctoral research station and the Jinlong Group Institute of Applied Science and Technology; it has 186 valid domestic and foreign patents, including 60 invention patents and 3 US patents; the company " The project "R & D and industrialization of high-efficiency and short-process technical equipment for copper pipes" won the only second prize for national scientific and technological progress in the same industry in 2016. Since 2008, the company has been ranked among the top 500 Chinese companies for many years. In 2018, it ranked 225th among the top 500 private enterprises in China and 131th among the top 500 private enterprises in China.
The company insists on the supremacy of customers and is committed to leading and promoting the trend of more energy-saving, healthier, smarter and more beautiful air-conditioning products. It has continuously introduced new types of copper pipes with high-strength thin-walls, high-efficiency thinner diameters and high corrosion resistance. To meet market requirements. The company's series of smooth copper pipes, internally threaded copper pipes, outer finned copper pipes, capillary copper pipes, etc. have become the air-conditioning and refrigeration manufacturers of Gree, Midea, Haier, Hisense, Oaks, GOODMAN, South Korean LG, and Japanese Daikin. The product of choice, the company's market share of precision copper pipes has consistently ranked first. While deep-cultivating precision copper tubes for air conditioning and refrigeration, the company developed large-caliber copper tubes for power cables and water transmission in buildings; copper alloy tubes for shipbuilding and marine industries; high-purity oxygen-free copper electronic copper tubes Used in the fields of electromagnetic microwave and computer cooling. The company's 45,000 tons of high-precision copper plates and joint ventures built by the company and the world-renowned German company KME were put into production in June 2018. Its copper plates and copper alloy plates and strips are mainly used for high-end automotive and mobile phone communications Devices, precision connectors, large-scale integrated circuits, electronic components and other fields, has won the certification of more than 10 well-known companies at home and abroad, is changing the high-precision copper strip in the past all rely on imports.
