Product Detail

Countersunk magnets,refer to neodymium magnets with counterbored holes. Countersunk magnets are used on boards and shelves asmagnetic holders,also could be used as magnetic locks for doors.Fixing curtain or door with a neodymium magnet is a good solution,but one of the big difficulty is firmly fix the magnet onto the woods.


Those neodymium magnets with countersunk holes for mounting magnets in place.


Fitting countersunk hole with a standard flat head screw is definitely a good and secure way.There are various size neodymium magnets with countersunk holes which can be used as holding magnets,either as discs or rectangles.


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


Supersonic processing: Neodymium magnets are brittle materials and inclined to crack with impact. The supersonic technique had been applied in making counterbored holes on small size magnet. 


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.
