Bonded Magnet Material And Process Options Injection Molding Compression Bonding Calendering Extrusion Bonded Magnet Material And Process Compression Bonding or Injection Molding? Injection Molding • Complex forms with good geometrical tolerances • Multi‐cavity tooling • Over and insert molding But • Expensive tooling • Lower magnetics (66% volume loading of magnetic powder) • NdFeB and ferrite Compression Bonding • Thin walled large L/D ratio rings • Simple low cost tooling • Higher magnetics (75% volume loading of magnetic powder) But • Simple geometries • Value added operations during pressing very difficult • NdFeB only CLEANING MAGNET TESTING MAGNET How long should my permanent magnet last? MAGNETIC APPLICATIONS
What Are Bonded Magnets Anyway? • Bonded magnets are composites of a permanent magnetic powder(s) embedded in a non‐magnetic matrix. • The matrix is typically a thermoplastic or elastomeric binder. • Common processing techniques are extrusion, injection molding, compression bonding, and calendering. • Exhibit excellent mechanical properties compared to fully dense rare earth and ferrite magnets. • End product has good finish and dimensional tolerances requiring no finishing operations. • Injection molded magnets can be formed into complex shapes and be insert or over molded directly onto other components to produce assemblies. • The non‐magnetic binder lowers the density of the magnet and dilutes the contribution of the magnetic powder. • They generate less magnetic output per unit volume than fully dense magnets. • The two most common magnetic powders are isotropic NdFeB and hard ferrite.
