Product Description

These neodymium cylinder magnets are applied in products that need strong magnetic force while space is limited. Electronics and electrical parts,  magnetic tools, and even in magnetic fishing.

and many other DIY 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.

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. 

Coatings available & Tests

Coatings Available: Zinc, NiCuNi, Epoxy, Gold, Silver, Tin etc.

Tests: Plating Thickness Test,Salt Spray Test,PCT Test
