Bonded magnet is one of the most important magnetic materials. Bonded magnets can be made from
either Ceramic/Hard Ferrite materials or Rare Earth NdFeB,
and are manufactured using both injection molding and compression
bonding techniques which are fully automated and are particularly suited to high volume production.
Injection molded magnets can be formed into complex shapes and be insert molded directly onto
other components to produce assembly parts. Compression bonded magnets offer higher magnetic
output than injection-molded magnets, but are limited to more simple geometries.
One of the greatest advantages of the injection molding process is that a high degree of shape
complexity is possible, i.e. gears, snap fits and undercuts. It is also possible to incorporate
shafts, bushes and other inserts into the process, simplifying the magnetic assembly manufacturing process.
