What is an injection molded NdFeB magnet?

     To put it simply, injection-molded NdFeB magnet is a new type of composite material made of NdFeB magnetic powder and plastic (nylon, PPS, etc.) polymer materials through a special process. Through the injection molding process, a magnet with both the high performance of the neodymium iron boron magnet and the high efficiency and high precision of injection molding is prepared. The unique process of injection molded neodymium iron boron magnets gives it some unique characteristics:

     1. It has both rigidity and elasticity, and can be processed into thin-walled rings, rods, sheets and various particularly complex shapes (such as steps, damping grooves, holes, positioning pins, etc.), and can be made into small extreme moments and multiple magnetic pole.

     2. Magnets and other metal inserts (gears, screws, special-shaped holes, etc.) can be formed at one time, and cracks and fractures are not easy to occur.

     3. The injection molded neodymium iron boron magnet does not need cutting and other mechanical processing, the product yield is high, the tolerance accuracy after molding is high, and the appearance is smooth.

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

     5. The plastic polymer material effectively coats the magnetic powder, which makes the injection-molded NdFeB magnet more anti-corrosive.

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

     Where are the injection molded NdFeB magnets used?

     It is used in automobile direction oil filters, mainly used in automation equipment, sensors, permanent magnet DC motors, axial fans, hard disk spindle motors HDD, inverter air conditioning motors, instrument motors and other fields.

     The advantages of injection molded neodymium iron boron magnets are high dimensional accuracy, can be integrated with other parts, and cost performance is high, but injection molded neodymium iron boron surface coating or electroplating has low corrosion resistance.
