① Characteristics and applications of rubber magnets: Rubber magnets are mainly divided into two categories: Isotropic Rubber Magnets and Anisotropic Rubber Magnets.
Characteristics: Rubber magnets are cost-effective, easy to process, and resistant to demagnetization. They also offer high dimensional accuracy and excellent corrosion resistance.
Applications: Isotropic rubber magnets, with their weaker magnetic properties, are commonly used in applications such as refrigerator magnets, printed products, and promotional items. On the other hand, anisotropic rubber magnets, which possess higher magnetic performance, are widely utilized in fields like micro motors and magnetic toys.

① Characteristics and applications of injection-molded magnets:
Characteristics: It combines rigidity and elasticity, allowing it to be processed into thin-walled rings, rods, sheets, and various complex shapes. It enables the simultaneous formation of magnets with metal inserts (such as gears, screws, and异型孔) in one process, reducing the risk of cracks and breakages. No cutting or mechanical processing is required for the magnet, resulting in high product yield, high dimensional accuracy, and a smooth surface after molding. The magnet also exhibits excellent internal uniformity, good surface field consistency, and strong corrosion resistance.
Applications: Injection-molded NdFeB magnets are primarily used in fields such as sensors, brushless motors, automotive electronic throttle pedals, automotive instruments, automotive instrument drives, automotive tachometers, and fuel gauges.
Characteristics: It enables the one-time formation of complex shapes and can be molded with inserts like shafts or bushings, reducing assembly steps and improving assembly precision. It has strong corrosion resistance, generally requires no surface treatment, and offers high temperature stability.
Applications: It is particularly suitable for precision machines such as automobiles and photocopiers. Many magnetic sensing instruments that need to operate in high-temperature and high-humidity environments must use this material.
Characteristics: Although the magnetic properties of injection-molded ferrite are lower than those of injection-molded NdFeB magnets, it is more cost-effective.
Applications: It is suitable for sensors and motor products with complex shapes and relatively lower magnetic property requirements.
