Working Principle：
The permanent magnetic chuck is embedded with high-performance rare earth permanent magnet materials, such as neodymium iron boron (NdFeB), which can generate a constant magnetic field and operate without an external power supply. By operating control devices such as handles or knobs, the magnetic circuit inside the permanent magnet material can be changed to turn the suction on/off.
Suction is on: When operating the control device, the magnetic circuit inside the permanent magnet material is connected, and the magnetic force is concentrated at the bottom of the suction cup, forming a strong suction force to firmly attract magnetically conductive objects.
Suction is turned off: When the control device is operated, the magnetic circuit inside the permanent magnet material is cut off, the magnetic force at the bottom of the suction cup is weakened, and the magnetically permeable object is separated from the suction cup.
Main Advantage：
1. Strong adsorption: Using high-performance rare earth permanent magnet materials, it can generate strong suction and safely lift various steel items.
2. Easy to operate: No external power supply is required, the operation is simple and easy to understand, and user-friendly.
3. Safe and reliable: Many permanent magnet suction cups are equipped with a safety release device, which can ensure that the adsorbed items will not fall even if the power is unexpectedly cut off, ensuring safety during lifting.
4. Durable: Made of high-quality materials, with good corrosion resistance and long service life.
5. Green and environmentally friendly: No need to consume electricity, green and environmentally friendly.
Application Scenarios：
It is widely used in machinery factories, mold factories, forging plants, steel mills, shipyards and other places where steel is used. It can greatly improve the handling efficiency of block, cylindrical, plate and irregular magnetic steel materials.
