HNJL Precision Copper Tube Technology Corporation is committed to the development and production of high-end high-precision copper tubes for air conditioning and refrigeration. It is an invisible champion enterprise in China's precision copper tube industry.
The company has a national-level enterprise technology center, a precision copper tube engineering research center of the Chinese Academy of Sciences, and a post-doctoral scientific research station; it has 286 domestic and foreign valid patents, including 86 invention patents and 13 US patents; And industrialization" project won the only second prize of National Science and Technology Progress Award in the industry in 2016.
The company continues to introduce new types of copper pipes with high strength, thin wall, high energy efficiency, narrow diameter, and high corrosion resistance to meet market requirements. The company’s series of smooth copper tubes, internally threaded copper tubes, external finned copper tubes, capillary copper tubes, etc., have become the leading air-conditioning and refrigeration manufacturers of Gree, Midea, Haier, Hisense,GOODMAN, LG,Daikin, etc. The preferred product, the precision copper tube produced by the company has consistently ranked first in the domestic and international market.
While cultivating precision copper pipes for air-conditioning and refrigeration, the company has developed large-diameter copper pipes for power cables, building water transmission and other fields; copper alloy pipes are used in shipbuilding, marine industry and other fields; high-purity oxygen-free copper electronic copper pipes Used in electromagnetic microwave, computer heat dissipation and other fields.
The 45,000 tons of high-precision copper strips jointly constructed by the company and the German company, a world-renowned precision copper strip manufacturer, were put into production in August 2018. It mainly produces new high-strength, high-conductivity, high-elastic, high-precision, and low-residual-stress Copper-nickel-silicon, copper-chromium-zirconium, copper-iron-phosphorus, copper-magnesium-phosphorus copper strips and hot-dip tinned copper alloy strips and foils which are urgently needed in the international market.
Products are widely used in automotive terminal connectors, precision connectors, high-end electronic components, large-scale integrated circuits, high-density lead frame manufacturing and other fields, meeting the needs of the high-end market of copper and copper alloy plates and strips in the Chinese and international markets. Effectively enhance the overall competitiveness of China's copper and copper alloy plate and strip industry.
