Injection Molded Magnet Material Specification Brochure injection molded magnets combine high magnetic strength with excellent physical properties to offer a variety of features and benefits including: High Magnetic Strength PLASTIC molded magnets offer the highest energy available in bonded ferrite, neodymium-iron-boron and samarium cobalt. The ferrite and SmCo materials are highly oriented during the manufacturing [...]
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?
