We would like to introduce Tokyo Ferrite Manufacturing Co., Ltd.'s "Plastic Magnet." A plastic magnet is a type of bonded magnet made from pellets that combine magnetic powder with resin, primarily formed through injection molding. It can be molded into complex shapes, is resistant to breaking, and if other components are integrated for a single molding process, it is possible to reduce the number of parts and assembly labor. [Features] ■ A type of bonded magnet primarily formed through injection molding ■ Can be molded into complex shapes and is resistant to breaking ■ Magnetic powder is oriented by applying a magnetic field in the mold to achieve high magnetic properties ■ It is possible to reduce the number of parts and assembly labor (design innovations can be expected at the planning stage) *For more details, please refer to the PDF document or feel free to contact us.

Our "Plastic Magnets" are characterized by their resistance to breakage and chipping, as well as their ability to be molded into complex shapes. They are used in various locations within automotive components, such as sensors and motors for various instruments and devices. For example, in hybrid vehicles (HV) where space in the engine room is limited, we have achieved the compactization of electric water pumps. Additionally, with extreme anisotropic orientation, we ensure a powerful discharge volume, making it suitable for mass production. ★ We are currently offering a "Case Study Document" featuring this example! You can view the document immediately via [PDF Download]. We are also providing materials that include magnetic properties and specifications. 【Features of Our Plastic Magnets】 ■ Low molding shrinkage rate, achieving high precision dimensions without post-processing ■ Minimal variation in magnetic force, allowing for free control of strength and flexibility ■ Capable of integrated molding with metal objects and other components, making it applicable for a wide range of uses. *Please refer to the document for a list of magnetic properties and specifications.

Sintered magnets are cost-effective magnets made primarily from iron(III) oxide (Fe2O3) and either barium carbonate (BaCO3) or strontium carbonate (SrCO3), produced using powder metallurgy methods. There are two types: "isotropic," which is pressed in a non-magnetic field, and "anisotropic" (both dry and wet), which is pressed in a magnetic field to impart magnetic directionality. Each type is categorized based on the magnetic characteristics shown in the magnetic property table. Thanks to the high coercivity characteristic of sintered magnets, they are less affected by external magnetic fields and self-demagnetization, and can accommodate flat or complex shapes! At Tokyo Ferrite, we conduct consistent production domestically from raw materials, ensuring high-quality manufacturing that addresses issues such as cracking and chipping. 【Features】 ■ Can be supplied stably and at low cost, offering excellent cost performance! ■ High coercivity makes them resistant to demagnetization, providing stable magnetic force! ■ Can achieve multi-pole magnetization on flat surfaces with 2 to over 10 poles, as well as on outer and inner circumferences! ■ We can also provide "pole anisotropic" and "radial magnets" as needed! *For more details, please refer to the catalog or feel free to contact us.
