Neodymium cylinder magnet consist of neodymium, iron and boron. The neodymium magnets retain much strongger magnetism than smco magnets and ferrite magnets. It is used in mining and quarry industries, engineering firms,construction sectors and many other custom projects. Neodymium cylinder magnets that we can manufacture are D40x20, D45x20, D45x25, D45x30, D50x20, D50x30, D55x25, D50x35, D60x30, D70x40, D70x50.We also produce customize magnets as customers' specifys. 


Our neodymium cylinder magnets are with NICUNI anti corrosion coatings,which will longer its using spam.Magnetization was processed from the axial direction(height direction).





Main Manufacturing Process


Melting: In the melting furnance,the neodymium,iron,boron materals form as compund ingots.


Hydrogen demolish: Shatter the ndfeb ingots into ndfeb powders.


Airflow mill:The ndfeb powders will be milled into micron sizes.


Shaping: Ndfeb powders in the mold will be pressed as ndfeb ingot.


Isostatic Pressing: Bearing the isostatic pressure is a important process to enhance the magnetism and of ndfeb material.


Sintering:The sintering procedure, were processed in a sintering furnace under 800~1300 vacuum environments.


Cutting: After the slice cutting process,the sizes of magnets will become suitable rectangles.


Grind and polish:Neodymium
magnets had been ground before they were magnetized.We could produce
magnets with standard tolerances for magnets from the range +/-0.07,
+/-0.05, +/-0.03, +/-0.02,and 0.01


Plating: Neodymium
magnets had been treated with electrical plating,otherwise it will rust
in the air. Platings that have been successfully applied to neodymium
magnets are epoxy plating,nickel plating,NICUNI plating,zinc palting.



Megnetization: Cylinder magnets are magnetized from the axial direction.
