Injection NdFeB magnet is a new compound material of NdFeB magnetic powder, plastic (nylon, PPS, etc.) high molecular material mixed by a special process. The high performance of NdFeB and the high efficiency and high precision magnetic substance of injection molding were obtained by injection molding. New materials and unique processes give them some unique characteristics:

1. Both rigidity and flexibility can be processed into thin wall ring, bar, sheet and various kinds of special complex shapes (such as the steps and damping groove, hole, positioning pin, etc.), producing little moments and multi-magnetic-pole.

2. The magnetic body and other metal inserts (gears, screws, special-shaped holes, etc.) can be formed in one time, which is not easy to crack or break.

3. The magnetic body does not need cutting or other mechanical processing, and the product has a high receiving rate, high tolerance precision and smooth surface after forming.

4. The use of plastic products makes the products thinner and lighter; Motor inertia and starting current are smaller.

5. The effective coating of plastic macromolecular material on magnetic powder makes the anti-corrosion effect of the magnetic body better.

6. The unique injection molding process improves the internal uniformity of the magnet and the surface magnetic field consistency of the magnet is better.

Where does Injection NdFeB magnetic ring can be used?

The direction is used in automobile engine oil filter, mainly used in automation equipment, sensors, permanent magnet dc motor, axial flow fan, HDD drive spindle motor, frequency conversion air conditioning, motor, instrument motor, etc.

PS: the advantages of injection-molded NdFeB magnet include high dimensional accuracy, which can be formed in one piece with other parts. The performance price is higher than that of other parts.
