China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Ferrite permanent magnet material is a kind of cost-effective magnetic material, according to the different manufacturing process can be divided into three types of sintered ferrite, bonded ferrite and injection molded ferrite, the following is the introduction of these three types of ferrite magnets, including characteristics, applications.
Sintered Ferrite Magnets;
Sintered ferrite is produced by pressing ferrite powder into shape and then sintering and curing it at high temperature. The magnets produced by this method have high density and magnetic properties, good mechanical strength and corrosion resistance, and are widely used in a variety of applications such as electric motors, loudspeakers, magnetic separators, sensors,...

Bonded Ferrite Magnets:
Bonded ferrite magnets are magnetic powder mixed with adhesive (such as resin or rubber), also known as flexible rubber ferrite magnets, molded or extruded through the molding process, and then cured to get the magnet, without high temperature sintering, the process is relatively simple, with good flexibility, easy to process, low-cost and other characteristics, the various anisotropic bonded ferrite is mainly used for automotive stickers, refrigerator stickers, magnetic door curtains, printed products, decorative items and so on. The anisotropic bonded ferrite is more used in micro motors, household appliances, magnetic toys and so on.

Injection Molded Ferrite Magnets
Injection molding ferrite magnets is the ferrite magnetic powder and plastic (such as nylon, PA, PP, etc.) after mixing, through the injection molding process to prepare, similar to bonded ferrite, but pay more attention to the molding process and the diversity of product shapes, and can be molded with other metal parts of the integrated injection molding with high dimensional accuracy, consistency and good, without the need for subsequent secondary processing, easy to complicate the shape of the seismic shock resistance and other advantages. Widely used in motors, sensors, automotive parts, household appliances, etc..
