Product Description

Screw countersunk magnets onto a wood frames. Countersunk hole neodymium magnets as discs or rectangles of outside dimensions. Various size of neodymium magnets with countersunk holes which can be used as holding magnets.

This magnet measures 45*15*15 mm is made of a grade N42 magnet. They are plated in a NICUNI coating for a metallic surface corrosion-resistant treatment. The North and South poles are on the largest flat sides that have countersink holes. The pull force of this magnet is about 30 lbs. Countersink magnet is a great item for use in personal projects as well as for crafts and closures and can also be used to help keep objects secured or fastened to any iron steel surface. Neodymium countersink magnets are perfect for use as magnetic holders

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.
