Magnet Purpose:This kind of NdFeB magnet with anti-rotation groove is usually used as an insert and placed into the mold cavity for secondary injection molding. The hot-melted plastic will be filled into the anti-rotation groove on the inner diameter of the magnetic ring until it matches the The end face of the magnetic ring is straight. Magnets that have undergone secondary injection molding will have higher precision and strength. Even under high-speed rotation or impact of 20,000 RPM, the magnetic ring will not separate from the plastic or become misaligned with the plastic.
