Today to introduce you to a more used in the field of motors, sensors, encoders and other composite magnets, its name is plastic bonded ferrite magnets, the following is the definition, composition, advantages and characteristics, as well as the application of the introduction.
Let's start with a picture of the appearance of a plastic bonded ferrite magnets
Meaning of plastic bonded ferrite magnets;Plastic bonded ferrite magnet is a kind of composite material magnet made by mixing ferrite magnetic powder with plastic substrate and through injection molding method, we also call this kind of magnet as injection molding ferrite magnet, this kind of magnet combines the magnetic properties of ferrite magnet and the mechanical properties of plastic substrate, cost-effective, with a wide range of application prospects.
Main components of plastic bonded ferritesIts main components are ferrite magnetic powder and plastic substrate. ferrite magnetic powder is the main source of magnetism, commonly used are SrFeO3 and BaFeO3. plastic substrate includes PA, PPS, PP, etc.. In order to improve the performance of magnets, lubricants, stabilizers, anti-aging agents, etc. are sometimes added.
Key performance characteristics of plastic bonded ferrites;The injection molding process can create a variety of complex shapes and structures for different application scenarios.Plastic substrates provide good mechanical strength and toughness, making magnets less prone to breakage.Plastic substrates typically have good corrosion and weather resistance, which extends the life of the magnet.Plastic substrates make the magnets lighter in overall weight, making them suitable for applications with stringent weight requirements.Compared to neodymium magnets, plastic bonded ferrite magnets are less costly and more economical.
