Ferrite permanent magnet material is a cost-effective magnetic material, it can be divided into three types of sintered ferrite, bonded ferrite and injection molded ferrite according to the different manufacturing processes, the following courage magnets Fu to introduce you to these three types of ferrite magnets, including features, main applications.
Sintered ferrite is a ferrite powder pressed into shape, and then sintered and cured at high temperature. Magnets produced in this way have high density and magnetic properties, good mechanical strength and corrosion resistance, and are widely used in a variety of fields such as motors, speakers, magnetic separators, sensors, and so on.
Sintered Ferrite Rectangular Hard Magnets
Bonded Ferrite Magnets (Rubber Magnets)
Bonded ferrite magnets are doped with adhesives (such as resin or rubber) in the magnetic powder, also known as flexible rubber ferrite magnets, through the molding or extrusion molding process, and then cured to get the magnet, without high temperature sintering, the process is relatively simple, flexible, easy to process, low-cost and other characteristics of a variety of anisotropic bonded ferrite mainly used for automotive stickers, refrigerator stickers, magnetic door curtains, prints, decorative items and so on. Anisotropic bonded ferrite is more used in micro motors, household appliances, magnetic toys, etc..

Injection Molded Ferrite Magnets
Injection molding ferrite magnet is a 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, without subsequent secondary processing, shape is not easy to complicate the advantages of good vibration resistance. Widely used in motors, sensors, automobile parts, household appliances and so on.
