Strong Neodymium Countersunk Magnet Description
Countersunk Magnet,use the “D”denoted the diameter of outside big ring magnet,and the“H”denoted the height of outside big ring magnet. Use the “d1”denoted the diameter of countersunk ,and “d2”denoted the diameter of inner ring, sometime will be mark the Countersunk angle withstand of “t”

Countersunk( d1=6mm d2=3mm thickness=0.5mm OR chamfer=45° )
Δ Magnet Detail Picture and Magnetized
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 iludes 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.
Tight production process control:
1.Production process continues to improve
2.Raw material control& fine pick
3.Advanced production equipment
4.Manual picking Sample making Machine inspection
Configure high-end detection equipment
The development of proprietary cutting technology,advanced precision machine tight production process control allowed Jintong to remain at the forefront of neodymium magnet manufacturers.
1.Average force meter ( Milling particle size inspection)
2.Magnetization characteristic automatic measuring instrument ( Issue demagnetization curve)
3.Magnetic testing equipment for measurements of Field Density and Field Strength
4.Hysteresisgraph for magnetic characteristic measurement.
