Injection bonded ferrite magnets

bonded ferriteInjection bonded ferrite magnets offer a combination of high magnetic strength and excellent physical properties. They offer large scale manufacture of shaped parts of close dimensional and magnetic tolerances, and therefore resulting in finished products of which usually need no further finishing machining. This deprives subsequent operations of the magnet and therefore reduces the total cost.

Application:

  • Copier and laser printer rolls
  • Permanent motor magnets
  • Rotors & other components
  • Magnetic rings for aerodynamic component
  • Color Monitor/TV purity convergence magnet

Bonders: PA6, PA12, PPS.

Characteristics:

  • Having high dimensional precision
  • Versatile shapes and specification
  • Impact-resistant, advanced surface treatment technology effectively protects.
  • Integrated forming
