Injection magnet is a kind of magnetic material that is made of resin (commonly PA or PPS) mixed with magnetic powder (iron oxide or rare earth magnetic powder) and injected into a mold. After being aligned by a magnetic field during molding, and it is called "anisotropic magnet" and without orientation called" isotropic magnet”. The main advantages of plastic magnets are: small density, high impact resistance, the products can be processed by cutting, cutting, drilling, lamination and embossing, and it is not easy to break when used, and it is easy to process into high dimensional accuracy, thin Products with walls and complex shapes can be made into molded products with inserts, which play a key role in achieving the goals of miniaturization, light weight, precision and performance of electromagnetic equipment. Since the injection magnet is injection molded, it can be made into magnets of various shapes or embedded in other accessories as required. Commonly used in water pump or oil pump rotors, hand-held electric tools, automotive instruments, sensors, etc. Due to the good corrosion resistance of the resin, injection magnets are often used in harsh working environments such as acid, alkali and oil.

Common shapes of injection molding magnets can be divided into: cylinder, ring, special-shaped magnet.

Injection magnet magnetization methods can be divided into: thickness magnetization, radial multi-pole magnetization, etc.

Injection magnet detection method: hysteresis curve, Gauss value (Gauss meter), flux meter (unit: Weber), etc.
