An injection ferrite magnet, a bonded magnet type, blends Strontium or Barium ferrite powder with thermoplastic binders like PA6 (Nylon 6), PA12 (Nylon 12), or PPS (Polyphenylene Sulfide). The powder-to-binder ratio varies widely, yielding diverse grades tailored for moisture absorption, magnetic strength, mechanical durability, and temperature resilience. This flexibility enables an injection ferrite magnet to meet specific needs, with the molding process excelling in crafting a vast array of shapes for intricate industrial applications.
Injection molding ensures an injection ferrite magnet achieves such precise tolerances that reworking is rarely needed, streamlining production. It also permits direct integration with polymer or metal parts, cutting assembly costs. Depending on the ferrite powder, magnetic orientation during molding may enhance the injection ferrite magnet’s performance, optimizing its magnetic properties for specialized uses.
