The products produced by the company are mainly used in automobile, construction machinery, national defense equipment, computer and other market fields; Customers are mainly distributed in China, the United States, Australia and other global markets.
The company is committed to the research and development, production and sales of heat exchangers, involving more than 500 products; With advanced technology and excellent quality, the annual sales volume of products exceeds 6.5438+0.8 million units. At present, the main supporting markets are faw liberation Company, FAW Liuzhou Special Purpose Vehicle Factory, Dongfeng Liuzhou Automobile Company, SAIC-GM-Wuling Company, Chongqing Changan Automobile Co., Ltd., Chery Automobile Company, Liuzhou Construction Machinery Co., Ltd. and Yuchai Machinery Co., Ltd..
The company has more than 300 sets of heat exchanger production and testing equipment, among which the imported German high-frequency tube-making machine, Swedish double-wave ribbon-making machine, American nitrogen-protected copper brazing furnace, American heat exchange performance wind tunnel test bench and British furnace temperature tracking tester are the most advanced key technical equipment for radiator manufacturing and testing in the world.
At the same time, the company is the first enterprise in China to master copper brazing technology and apply it to mass production, and the sixth enterprise in the world to master and apply copper brazing technology after UAR and Radac in the United States, Shaaz in Russia, Berry in France and Najico in Japan.
Through introduction, digestion and re-innovation, the company successfully took the lead in mastering three core technologies of domestic tube-and-belt heat exchanger industry: copper brazing technology, double-wave heat dissipation belt structure technology, high-pressure heat exchange core and unit structure technology.
The company has passed ISO900 1, TS/ 16949 quality system certification.
The company's testing center has obtained the laboratory accreditation certificate of China National Accreditation Committee for Conformity Assessment.
The company's technology research and development center is "Guangxi Internal Combustion Engine High Temperature Heat Exchange Engineering Technology Research Center" in Guangxi Zhuang Autonomous Region.
In 2008, the company was awarded the Centennial Achievement Award of China Internal Combustion Engine Industry by China Internal Combustion Engine Industry Association.
In 20 10, the company was awarded the title of "Leading Enterprise in Internal Combustion Engine Parts Industry in China" by China Internal Combustion Engine Industry Association.
Adhering to the tenet of "achieving customers, achieving eight goals and achieving self", the company keeps pace with the times with an enterprising attitude and builds its own brand!
While continuously improving product quality and technical level, the company pays more attention to the construction of talent team. The company has a professional R&D team of heat exchanger technology with high technical level and rich experience in R&D and engineering practice. In the long-term R&D process, referring to the most advanced R&D system mode in the industry, a set of engineering database of cooling unit structural parameters matched with automobile engines is established, which can efficiently optimize the design of the cooling system of the engine system and quickly provide a complete cooling system president and cooling unit design scheme.
High frequency pipe making machine &; Wind tunnel test equipment
The company's existing testing technology center is a first-class open testing service platform in the same industry in China, and obtained the laboratory accreditation certificate of China National Accreditation Committee for Conformity Assessment on 20 10. Since its completion in 2004, it has provided paid inspection services for many domestic peer companies, and played its due role in promoting the technical progress and development of China's automobile radiator industry.
The company's copper brazing technology is the most advanced heat exchanger manufacturing technology in the world.
This technology was invented by ICA in 1999. In 2000, this new technology was put into industrial application in UAR company of the United States. By the end of 2008, this new technology has been popularized and applied in Radac of the United States, Shaaz of Russia, Berry of France, Najico of Japan and our company. At present, our company is the only heat exchanger manufacturer in China that has successfully introduced this new technology.
Continuous nitrogen shielded brazing furnace
Copper brazing technology adopts green, environmental protection, high strength and high temperature brazing alloy as brazing solder. Brazing solder consists of 75% copper, 5% nickel, 15% tin and 5% phosphorus. Among them, tin and phosphorus play the role of welding AIDS, and basically volatilize and escape after the completion of the high temperature brazing process at nearly 700℃. The remaining copper and nickel form a copper-nickel alloy solder joint with high strength, high heat transfer rate, corrosion resistance and high temperature resistance at the solder joint.
Compared with traditional brazing technology, copper brazing technology can improve brazing strength by nearly 3 times, heat exchange performance by 3%, corrosion resistance by 5- 10 times, work stably at 300℃, contain no lead metal, and can be recycled 100%.
The copper heat exchanger manufactured by copper brazing technology has the advantages of high strength, high heat exchange efficiency, corrosion resistance, high temperature resistance, long service life and lead-free pollution, and can work for a long time under harsh working conditions.
