Ningbo Jinji Strong Magnetic Material Co.,Ltd.

  Ningbo Jinji Strong Magnetic Material Co.,Ltd. founded in 1998, which includes Rare Earth Magnet Material Engineering and Technical Development & Research Center and sales branches in Shenzhen and Beijing, mainly produces and handles and permanent magnet motor, 38% of staffs are magnetic specialists, engineers and technicians.
  On the basis of summing up domestic and foreign experience on NdFeB magnet Production and improved technology, creatively combing mold-forming technology of international powder metallurgy to adopt mold direct once forming to produce NdFeB magnets, this technology is initiated in China, and meets international advanced level. Not only the consistency and uniformity of NdFeB magnets produces with this new technology are better but also several traditional processes such as isotropic press, wire cutting and drilling are canceled. Based on this technology, we also developed "Radially Oriented Ring Magnet". The NdFeB magnet application fields are broadened. We already attained several patents on production technology through years' research and development. As a result of strengthened administration on every process and improved management level, the company developed quickly, obtained ISO9002 international qualification system certificate in April 2000.
  We can offer high-energy magnets, such as N45,N42N,N38SH, N33UH and N30EH, is one of remarkable bases of production and export of NdFeB magnet, with capacity of 600 Ton NdFeB magnets per year.
