Ningbo Tongchuang Strong Magnet Material CO.LTD. is a high-tech company specializing in NdFeB magnet manufacturing, researching, developing and applications, which is located in Ningbo,(a coastal city in China, with sound business and transportation environment).
Tongchuang has staffed with a team of experienced professionals in magnetism and magnetic applications that benefits us with many patented and unique magnet production techniques and processes. Our sintered NdFeB magnets are in full grades and high quality but low cost, with four distinct features of High (i.e.high corrosion resistance), Low (i.e. low temperature coefficients), Big (i.e. big dimensions) and Small (small size). With integrated QC system and advanced test equipments, all our manufacturing procedures are operated well under ISO 9000. All sintered Nd-Fe-B magnets in our company are inspected in accordance with ROHS requirements.
Tongchuang is growing as one of the leading NdFeB magnet manufacturers in China, through its investment expending of production facilities, management level and skill upgrading and innovation on production technologies.
Due to the high quality and various specifications, our products has been exported to Europe(Germany, Italy etc) and the USA as well as in other East Asia like Korea, Japan etc.Taking Producing first class products, Providing high-grade service as our business motto, we will try to provide all clients with high quality and consistency NdFeB magnets
Providing customers our best quality products and best services is the commitment Tongchuang. Customers' satisfication is always the foucus in our management and production actitvities.
