Auto Ac Expand Tube Joint :applied in R134a auto ac refrigeration system. In order to decrease the weld joint to avoid the leakage, we change press plate and tube braze structure into press plate and expand tube . Below construction has been successful in ZOTYE - T22.S21.JT11 ,mass production quantity reach into 200,000pcs with stable quality .The coaxial tube of automobile air conditioning system is mainly used in R134a refrigerant air conditioning system. It can enhance the refrigeration effect of automobile air conditioning system. It has begun in the ZOTYE project A40 and JAC project S7.M432.

As one of the major research institutes in China's non-ferrous metal industry, Hunan Nonferrous Metals Institute has made outstanding achievements in the research and development of non-ferrous metal mineral resources and the development and production of new materials. So far, there have been 441 scientific research achievements, including national and provincial level. The above invention awards, 102 scientific and technological progress awards, and 29 patents, some technologies and products have filled the domestic gap. In recent years, the institute has conducted a lot of in-depth experimental research in the field of low-carbon and high-efficiency beneficiation technology, and has obtained a number of scientific research results.
Copper, Lead and Zinc complex multi-metal mineral processing technology, mineral processing technology has been a recognized technical problems. After many years of research, Hunan Nonferrous Academy has made a major breakthrough. Its "complex copper, lead and zinc high-performance beneficiation separation technology and industrial application" technology can improve copper recovery rate of 5-15% and lead recovery rate of 3-10%, setting a complex copper-lead-zinc sulfide ore concentrate grade since the founding of New China. The highest level of indicators such as recovery rate was awarded the first prize for scientific and technological progress in the national non-ferrous metals industry. Wang Dianzuo, former deputy dean of the Chinese Academy of Engineering and academician of the two academies, believes that this research has filled the gap in the domestic copper-zinc-polymetallic ore dressing technology. At present, the technology has been in Tibet Kay Mozhugongka concentrator, Silver Mountain small iron ore non-ferrous metals, lead and zinc Qibaoshan Jiangxi, Hunan Baoshan lead-zinc and other domestic and foreign enterprises successful application, create direct economic benefits for the enterprise 3 More than 100 million yuan.
Not long ago, the institute completed the Congo (gold) SICONIMES copper mine copper oxide cobalt ore beneficiation pilot project, the project creatively used copper oxide cobalt asynchronous flotation copper, medium mine re-grinding, medium-mineral re-election and innovative high efficiency New technologies such as mineral processing chemicals can create hundreds of millions of dollars in economic benefits for enterprises every year.
Hunan Nonferrous Metal Research Institute announced that the hospital shortly before the completion of the Congo (DRC) SICONIMES copper ore oxide copper and cobalt ore beneficiation pilot project, beneficiation index achieved a major breakthrough, copper recovery of 85% and the recovery of cobalt from 38% increased to 61%, setting a new high in research results in the same industry at home and abroad. Recently, large domestic and foreign enterprises COTCO Mines Ltd., North Corporation, white silver Nonferrous Metals Group, Zhejiang Hurray, etc. have come to Hunan colored homes, mineral processing technology to discuss cooperation matters.
