Injection Bonded Ferrite Magnets

Overview

Injection Bonded Ferrite Magnets are a combination of good magnetic strength and strong physical properties. The magnets can be easily manufactured on a large scale with close dimensional tolerances and need no finishing operations, thus saving costs. Ashvini Magnets offers a range of injection bonded ferrite magnets that are recognised for high durability and utility. The magnets can be manufactured as per design or custom designed to suit the applications.

Bonded Ferrite is injection molded using Nylon 6, Nylon 12 and PPS which can be easily aligned in the mold to achieve higher magnetic properties and custom waveforms.

Characteristics

  • Huge variety of shaping possibilities for intricate and complex shapes
  • Very good edge strength and greater resistance to Impacts.
  • Dimensional precision with very high consistency without any additional processing.
  • Consistent magnetic characteristics built to suit custom assemblies.
  • Non-corrosive  due to their anti-oxidation characteristics
  • Simple to complex multi-pole magnetization possible.
  • Isotropic/Anisotropic Magnets can be manufactured with very high efficiency and reliability
  • Reduction in weight of the magnet as compared to sintered magnets.
  • Monobloc molding (Insert molding/Over molding) possible thereby reducing extra assembly operations.
  • Highly competitive for multi-pole motor and sensor magnets
  • High Degree of machinability
