Speaking of countersunk magnet , maybe you will feel strange, then let me give a few examples to recall your memory.

On the toys of the children at home, especially those robots, there are some big screws on them. Although they think it should be easy to screw 

them down, it’s really hard to uninstall actually. It seems that there is something in it. Like a strong pull force . That is a round neodymium magnet with countersunk.the countersunk magnet have a double protection.


ΔDisc Magnets Production Flow (Quality Control)  

① Neodymium magnet production processing

Hydrogen explosion+Jet  milling+Sintering+Hypoxia operation process

Sintered NdFeB is the most  widely used rare earth/ permanent magnet material. The metallurgy powder was process  into micro-powder through special Sintering Craft. The production process includes formula design, cast string, hydrogen explosion,Jet  milling, mixing, molding,Vacuum furnace Sintering , grinding, polishing, surface treatment(coating), packaging . through the( HD+JM+LOP )craft ,the neodymium magnet was feature with  high coercivity and high working temperature.
