Precise inject magnet include Anisotropic and isotropic magnet. Isotropic magnet magnets mainly used in colour TV, and Anisotropic magnet mainly used in the magnetic roller of laser printer, DC motor, small generator, relay, sensor, air-conditioner. Precise plastic part mainly used in field:Appliance (Camera, pickup camera), motor, hardware.
As a new production process for permanent magnetic material, Ferrite magnets produced with Injection moulding process remain ferrite magnets with much higher magnetic properties, meanwhile ,which exert advantages of high efficiency and high precision on injection moulding, as well as provided the injection plastic magnets with particular characteristics.
1) with hardness and elasticity, and could be processed into thin ring easily.
2) Could be injection moulded with axis at one time, simplify assembling,ensure precision. Complex shape and precise tolerance can be achieved.
3)In the condition of heat-melting, they are of even density, excellent consistency.
4) Produced by injection with mixture of ferrite powder and plastic binder. Be of excellent corrosion resistance as the ferrite powder is covered by plastic binder;
5). Density: 3.6---3.8g/cm3
6). Operating temperature range from �0 0C---130 0C .

Applications:
Magnetic rollers for copier and laser printer
Permanent motor magnets
(rotors & other components)
Magnetic rings for aerodynamic component
Color Monitor/TV purity convergence magnet
Binders: PA6, PA12, PPS.

Characteristics:
Having high dimensional precision
Versatile shapes and specification
Impact-resistant.advanced surface treatment technology,effectively protect.

Magnet rollers

Magnet roller & sleeve series: mainly produce magnet rollers & sleeves for laser printer cartridge. We imported advanced technology from Germany and successfully developing and manufacturing expendable parts magnet roller (plastic bonded ferrite magnet) and aluminum sleeve. Now we could custom make many different magnet rollers & sleeves to supply clients of local and abroad, which have a prefect performance on matching with almost every toner, and resulting 1.4---1.5 printing density, and successfully avoid following problem occur: period whiteness, white-spot and background, etc.

Magnet rollers which are under mass production can be suitable in the following toner cartridges. As follows:
