Company Profile
Established in 2003, Hesheng Magnetics is one of the earliest enterprises engaged in the production of neodymium rare earth permanent magnets in China. We have a complete industrial chain from raw materials to finished products.
Through continuous investment in R&D capabilities and advanced production equipment, we have become the leader in the application and intelligent manufacturing of neodymium permanent magnets field ，after 20 years development,and we have formed our unique and advantageous products in terms of super sizes, magnetic Assemblies，special shapes, and magnetic tools.
We have long-term and close cooperation with research institutes home and abroad such as China Iron and Steel Research Institute, Ningbo Magnetic Materials Research Institute and Hitachi Metal,which has enabled us to consistently maintain a leading position of domestic and world-class industry in the fields of precision machining, permanent magnet applications, and intelligent manufacturing.
We have over 160 patents for intelligent manufacturing and permanent magnet applications, and have received numerous awards from national and local governments.
Coating for strong neodymium magnets
Sintered NdFeB has the strongest magnetic properties, but it has one of its biggest weaknesses, its corrosion resistance is too poor, so sintered NdFeB needs to be plated.Because the production process of sintered NdFeB is a powder metallurgy process, there will be small pores on the surface of the product. To make the plating layer more dense and improve the corrosion resistance, the passivation sealing treatment before plating is very important.
Magnet Coating Types Display
Support all magnet plating , like Ni, Zn, Epoxy , Gold, Silver etc.
Ni Plating Maget: Good anti-oxidation effect, high gloss apprearance,long servie life .t
