1. Rubber Magnet
① Features and Applications of Rubber Magnets
It is mainly divided into Isotropic and anisotropic rubber magnets.
Features: Low price, convenient processing and not easy to demagnetize, with high dimensional accuracy and corrosion resistance.
Application: Isotropic rubber has weak magnetic properties and is mainly used in refrigerator magnet assembly, printed products, and promotional items. The anisotropic rubber magnet has high magnetic properties, so it is widely used in the fields of micro motors and magnetic toys.

2. Injection Magnet
① Features and Applications of Injection Magnets
A. Injection NdFeB
Features: It has both rigidity and elasticity, and can be processed into thin-walled rings, rods, sheets and various special and complex shapes. It can make magnets and other metal inserts (gears, screws, special-shaped holes, etc.) formed at one time, and cracks are not easy to occur. Does not need cutting and other mechanical processing, the product yield is high, the tolerance accuracy after molding is high, and the surface is smooth, the internal uniformity of the magnet is good, the surface magnetic field consistency is good, and the corrosion resistance is strong.
Application: Mainly used in sensors, brushless motors, automotive electronic accelerator pedals, automotive instruments, automotive instrument drives, automotive tachometers, fuel gauges and other fields.
B. Injection SmCo
Features: It can realize one-time molding of complex shapes and can be molded with inlays such as shafts or bushings at one time, reducing assembly processes and improving assembly accuracy. It has strong corrosion resistance, generally does not need surface treatment, and has high temperature stability.
Application: It is especially suitable for precision machines such as automobiles and copiers, many magnetic induction instruments that require high temperature and high humidity environments must use this material.
C. Injection Ferrite
Features: The magnetic properties of injection ferrite are lower than injection NdFeB magnets, but its price is cheap.
Application: It is suitable for use in sensors and motors with complex shapes and relatively low magnetic performance requirements.
