Bonded Injection Moulding Ferrite Magnet for Sensor, Permanent Ndfeb Plastic bonded sensor magnet, Ferrite injection bonded ring magnet, Bonded magnet Assembly China supplier
Bonded Injection Moulding Ferrite Magnet for Sensor – Precise injection bonded ferrite magnets include Anisotropic and isotropic magnet. Isotropic 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. Plastic Bonded Magnets for Car Light Control
Bonded magnet materials can be created through Injection Molded and can be made from NdFeB, Strontium Ferrite or a combination of the two. Bonded magnets that are created through injection molding can be molded into complex shapes and also molded directly onto components. Bonded magnets can also be created through the process of compression bonding which offer higher magnetic output but are limited to simpler geometries than Injection Molded materials. Compression Bonded magnets can be made from either NdFeB or SmCo powders.
