Countersunk magnets are composed of neodymium magnets with a countersunk hole. Countersunk hole neodymium magnets are with various sizes of discs or rectangles shapes. Round countersunk magnets are perfect as magnetic fixers. Countersunk magnet is a good DIY activity for holding tools and objects,furnitures and more...
The neodymium countersunk magnet is a neodymium, iron, and boron magnetic alloy blend.The magnets are with anti corrosion platings.
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.
