What are bonded Magnets?
Bonded magnet is one of the most important magnetic materials. It opened a new world of application possibilities. Thermo-elastomer and thermoplastic resins can be blended together with a variety of magnetic powders to form an injection molded, compression and flexible magnets.
Bonded magnet of ours can be divided into Compression Molding NdFeB, Injection Molding NdFeB, and Injection Molding Ferrite according to the processing methods and materials.
injection molded magnet is one of the more important developments in magnetic materials, it has opened a new world of application opportunities. Similar to plastic injection molding, magnet injection molding process is by mixing the magnetic powder together with the polymer binder, heated in the injection machine and shooting the melted mixtures into the mold to achieve different shapes of products.
Injection molded magnets can be formed into complex shapes and be insert molded directly onto other components to produce assembly parts. Compression bonded magnets offer higher magnetic output than injection-molded magnets but are limited to more simple geometries.
